On a new Theorem Involving Generalized Mellin-Barnes Type of Contour Integral and Srivastava Polynomials
Authors: Agarwal Praveen
Published: April 2013

Motivated by resent work of Agarwal [1], the author is establish the new theorem associated with the H - function (Generalized Mellin-Barnes type of Contour Integral), which was introduced and study in a series of papers by by Inayat -Hussain ([12], [13]).Theorem involves a product of the H -function, Generalized hypergeometric functions and Srivastava polynomials. The convergence and existence condition, basic properties of H -function were given by Buschman and Srivastava ([7]). Next, we obtain certain new integrals by the application of our theorem. These results, besides being of very general character have been put in a compact form avoiding the occurrence of infinite series and thus making them useful in applications. Our findings provide interesting unifications and extensions of a number of new results.
Sequences of Inequalities Among Differences of Gini Means and Divergence Measures
Authors: Taneja Inder J.
Published: April 2013

In 1938, Gini [3] studied a mean having two parameters. Later, many authors studied properties of this mean. In particular, it contains the famous means as harmonic, geometric, arithmetic, etc. Here we considered a sequence of inequalities arising due to particular values of each parameter of Gini’s mean. This sequence generates many nonnegative differences. Not all of them are convex. We have established new sequences of inequalities of these differences. Some refinement inequalities are also presented. Considering in terms of probability distributions these differences, we have made connections with some well known divergence measures.

Published: April 2013

Pollution of the environment components in many cases presents unacceptable risks to human health and the environment. Risk analysis is one of the tools which help to find a socially acceptable level of the environmental quality. Evaluation of the environmental impacts can be the base for the optimal spatial arrangement and functional use of territory - landscape optimization. In Slovakia, LANDEP methodology based on the principles of sustainable development, is very often used for landscape planning. The paper deals with environmental risk assessment of components of environment (air, water, soil, waste, etc.). The results are used as a base for design of the optimal spatial setting and functional utilization of the land - landscape optimization.

Limitation of bridge’s carrying bearing capacity due to aging and deterioration is a common problem faced by road administration and drivers. Rehabilitation of bridges including strengthening may be applied in order to maintain or upgrade existing bridge parameters. The case studies of strengthening of two small bridges with high modulus prestressed CFRP strips have been presented in the paper. The first one - reinforced concrete slab bridge - and the other - composite steel-concrete girder bridge - have been successfully upgraded with quite new technology. In both cases the additional CFRP reinforcement let increasing of bridge carrying capacity from 15 till 40 metric tons. The CFRP strip prestressing system named Neoxe Prestressing System (NPS), developed by multi-disciplinary team and tested at full scale in Rzeszow University of Technology, has been also described in the paper.
The Role of Forests in Mitigating Climate Change – a Case Study for Europe
Authors: Gálos Borbála , Hänsler Andreas , Kindermann Georg , Rechid Diana , Sieck Kevin , Jacob Daniela
Published: April 2013

- A regional-scale case study has been carried out to assess the possible climatic benefits of forest cover increase in Europe. For the end of the 21st century (2071-2090) it has been investigated, whether the projected climate change could be reduced assuming potential afforestation of the continent. The magnitude of the biogeophysical effects of enhanced forest cover on temperature and precipitation means and extremes have been analyzed relative to the magnitude of the climate change signal applying the regional climate model REMO. The simulation results indicate that in the largest part of the temperate zone potential afforestation may reduce the projected climate change through cooler and moister conditions, thus could contribute to the mitigation of the projected climate change for the entire summer period. The largest relative effect of forest cover increase can be expected in northern Germany, Poland and Ukraine. Here, the projected precipitation decrease could be fully compensated, the temperature increase could be relieved by up to 0.5 °C, and the probability of extremely warm and dry days could be reduced. Results can help to identify the areas, where forest cover increase could be the most effective from climatic point of view. Thus they can build an important basis of the future adaptation strategies and forest policy.

Published: April 2013

The purpose of this study was to assess the quality of life of patients who underwent anterior cruciate ligament single-bundle reconstruction (ACLR) which involves reconstructing the ligament using autologous graft (semitendinosus and gracilis tendon). This is a retrospective study undertaken between the 1st of January 2010 and December 31, 2011 at the Clinic of Orthopedics and Traumatology Tîrgu-Mureş, involving 30 patients (6 women, 24 men), 17 to 54 years old (mean age of 30.13 years). All the patients underwent ACLR, with the above mentioned technique. The instrument chosen to assess the quality of life was the Short-Form 36 (SF-36) Questionnaire, completed by telephone. This questionnaire has 8 scales which are noted according to the received answers: Physical Functioning (PF), RF (Role Physical), BP (Bodily Pain), GH (General Health), VT (Vitality), SF (Social Functioning), RE (Role Emotional) and MH (Mental Health). The best way to score these scales is by comparing them to the healthy population, which is why this study uses normbased scales where the mean value is 50 and the standard deviation is 10. The scales used in the questionnaire are showed the next results: mean norm-based PF 49.19, RF 46.11, BP 49.82, GH 52.19, VT 52.14, SF 50.43, RE 41.36 and MH 47.18. The general Physical Component showed a mean of 48.93 and the Mental Component a mean of 47.33, close to the standard mean of 50. All these results were included in the standard deviation, which showed that the patients’ quality of life was very close to the quality of life of the normal population. Patients who have a history of ACLR tend to have a quality of life similar to the normal, healthy population.

Published: April 2013

Our results were obtained on a total of 101 cases and the presence of the colosigmoid trunk was encountered in 54.46% of cases, with seven types of branching variation. We were able to compare our results with those of Lippert, noticing that the classical anatomy only mentions (without details) the presence of the colosigmoid trunk, while other authors do not even mention it. The anatomical variations of the colosigmoid arterial trunk are: 1. from the colosigmoid trunk originate the left colic artery and a sigmoid trunk that gives origin to all three sigmoid arteries (14.85% of cases); 2. from the colosigmoid trunk originate the left colic and the superior sigmoid arteries (18.81% of cases); 3. from the colosigmoid trunk originate the left colic artery and a sigmoid trunk that give origin to two sigmoid arteries, superior and inferior, an aspect found in 4.95% of cases; 4. a colosigmoid trunk that give rise to the inferior sigmoid artery and to a lower trunk that give the left colic artery and the superior sigmoid artery (5.94% of cases); 5. a colosigmoid trunk that give origin to the left colic, middle colic and superior sigmoid arteries in 5.94% of cases; 6. a colosigmoid trunk that splits into a colic branch which further gives origin to the left and middle colic arteries and into a sigmoid branch that will give the superior and inferior sigmoid arteries (1.98% of cases); 7. a colosigmoid trunk that gives origin to the middle colic artery (for the transverse colon), to the left colic and superior sigmoid arteries (1.98% of cases).
Clinical assessments on the dento-maxillary anomalies

Published: April 2013

The dento-maxillary anomalies, through their
characteristics, ie widespread population mass, the
impact that occurs at a personal level and in society
and the etiological factors, have become a public health
problem, ranking first in dental diseases, prior to dental
caries and periodontitis. The prevalence of the dentomaxillary
anomalies vary by study population, age
group, geographical environment, socio-economic
factors and the historical moment of the research. This
clinical study was conducted over a period of five years,
from 2006 to 2011, on a number of 320 study models,
for diagnosis and treatment strategies. The study
allowed the assessment of increasing trends of dentomaxillary
anomalies, with a frequency of 44% in large
cities, while in subjects with caries and periodontitis, the
index is 41%. The large percentage differences reported
between some authors are mainly due to patients, but
also to different research methods, doctors training
and errors of interpretation. The orthodontic treatment
should answer to the expectations of the patient, thus to
restore the morpho-functional integrity and the dentomaxillary
functions, with minimal biological sacrifice.

Published: April 2013

Lipids and fatty acids (FA) composition of three Black Sea macroalgae Cladophora vagabunda,Ceramium rubrum and Cystoseira barbata were studied. Fatty acids composition was analyzed by GC/MS. Total lipids content varied widely among the species and ranged between 0.66 and 0.98 g per 100 g fresh weight. Generally, saturated fatty acids were major components (62-71%), with 16:0 as the most abundant saturate (41- 57%). Total polyunsaturated FAs and monounsaturated FAs ranged from 28% to 38%. The green alga Cladophora vagabunda showed higher C18 PUFAs contents than did C20 PUFAs while for red alga Ceramiumrubrum the trend was opposite. Cystoseira barbata belonging to the group of brown algae showed similar amounts of C18 and C20 PUFAs contents. Cladophora vagabunda was rich in linoleic acid and Ceramiumrubrum in arachidonic acid (AA) while Cystoseira barbata was rich in both linoleic acid and eicosopentaenoic acid. All of the studied species had a nutritionally beneficial n6/n3 ratio (1.24-2.84:1).

Authors: Vamanu Emanuel
Published: April 2013

The antioxidant action of ethanolic extract from Agaricus bisporus which is available in the

supermarkets of Bucharest, Romania, was assessed by determining its reducing power and its radical scavenging activity. The determinations were made by analyzing the freeze-dried ethanolic extract. The radical scavenging activity was determined using 2, 2-diphenyl-1-picrylhydrazyl (DPPH), superoxide radical, nitric oxide radical and hydrogen peroxide scavenging assays. Total phenols, flavonoids, ascorbic acid, β-carotene and lycopene were also determined. The ethanolic extract from A. bisporus could be a natural antioxidant and antimicrobial source against the tested organisms, as demonstrated by the minimum inhibitory concentration values.

Authors: Zaharia Ionut , Diaconu Ioana , Ruse Elena , Nechifor Gheorghe
Published: April 2013

Transport through liquid membranes of various chemical species is a viable method for different applications in analytical or technological domain. This paper presents the transport and separation results of two compounds of pharmaceutical importance: salicylic acid and aspirin, using bulk liquid membrane technique. We studied the effect of the feed source and receiving phase pH on the transport efficiency of the two compounds throught chloroform membrane. These results were correlated with speciation diagrams of salicylic acid and aspirin. The speciation diagrams shows that in these pH conditions, for aqueous phase of the membrane system, the two compounds are mostly undissociated form and therefore active for transport. In this system it can be achieve separation of the two compounds, salicylic acid and aspirin, using a suitable complexing agent in the feed source such as Fe3+. In this way salicylic acid forms an inactive complex structure for transport while aspirin crosses the membrane and it is recovered in a percentage of 80% in the receiving phase membrane system.

3,6-bis(2,3-dihydrothieno [3,4-b][1,4]dioxin-5-yl)-9-tosyl-9H-carbazole (EDOTTsCz) was synthesized and electrochemically polymerized on glassy carbon electrode (GCE) in 0.1 M tetrabutyl ammonium tetrafluoroborate (NB4BF4)/acetonitrile (CH3CN). Alternating copolymer was formed by CV method. Modified polymer electrode was characterized by Fourier transform Infrared Spectroscopy-Attenuated Transmission Reflectance (FTIR-ATR), Cyclic voltammetry (CV), Scanning electron microscopy-Energy dispersive X-ray analysis (SEM-EDX), Atomic force microscope (AFM) and Electrochemical impedance spectroscopy (EIS). Capacitive behaviors of the modified GCE were defined via Nyquist, Bode-magnitude, Bode-phase and Capacitance plots. A modified copolymer electrode provides enhanced capacitance evaluation, which may results in performance in energy storage devices.

Published: April 2013

The objective of this study is the evaluation of the opportunity to use an inorganic oxygenated compound as ammonium nitrate or urea, to reduce fossil fuels pollution. Our research takes into account the ammonium nitrate water solution, mixed with diesel fuel, in various proportions, as fuel for a diesel engine. The results are very promising, the reduction of the consumption is near 20% and the reduction of particulate matter emission is near 75%, without particulate filter on the exhaust pipeline. The paper intends to explain the ammonium nitrate influence in this process. It is to consider the role of the oxygen which is released in the process of ammonite decomposition in the engine cylinder and the role of the atomic nitrogen, which results in the same process, as fuel with a great energetic value. The energy released at the formation of a nitrogen molecule, N2, with his triple chemical bond N≡N, is almost the same as the carbon burning but without CO2 as reaction product.

Published: April 2013

The catalytic activity of catalysts for bioethanol conversion to hydrocarbons was tested by cracking nhexane in a glass microreactor in the temperature range of 623 to 823K. The microreactor is a tubular one with axial thermocuple measurements in flow, initially for some experiments in nitrogen and for others by hydrogen. Reaction products were collected and analyzed as gaseous samples by Gas Chromatography. The samples of Me-ZSM-5 zeolites (Me=Fe, La, Ce) were prepared by impregnation method. All the prepared samples had a metal content of approximate to 3 % wt. ZSM-5 zeolite was synthesized by using a structure direct agent, namely tetrapropylammonium hydroxide (TPAOH) and hydrothermal crystallisation method under alkaline conditions according to reported procedures.
Regeneration of used engine lubricating oil by solvent extraction
Authors: Sterpu Ancaelena-Eliza , Dumitru Anca Iuliana , Popa Mihai-Florinel
Published: April 2013

Huge amounts of used lubricating oils from automotive sources are disposed of as a harmful waste into the environment. For this reason, means to recover and reuse these wastes need to be found. Problems arising from acid treatment include environmental problems associated with the disposal of acid sludge and spent earth, low product yield (45-65%) and incomplete removal of metals. The processes of re-refining of used lubricating oils depend greatly on the nature of the oil base stock and on the nature and amount of contaminants in the lubricant resulting from operations. The study was carried out on a sample of 15W40 type used oil collected from one automobile. The re-refining process of used oil consists of dehydration, solvent extraction, solvent stripping and vacuum distillation. This study aims to investigate a process of solvent extraction of an alcohol-ketone mixture as a pre-treatment step followed by vacuum distillation at 5 mmHg. The primary step was conducted before the solvent extraction that involves dehydration to remove the water and fuel contaminants from the used oil by vacuum distillation. The solvent extraction and vacuum distillation steps were used to remove higher molecular weight contaminants. The investigated solvent to oil ratios were 2, 3, 4, 5 and 6. The solvent composition is 25% 2-propanol, 50% 1- butanol and 25% butanone or methyl ethyl ketone (MEK). The percentage of oil recovery for the solvent to oil ratio of 6:1 is further improved, but for the ratio values higher than 6:1, operation was considered economically not feasible. Finally, the re-refined oil properties were compared with the commercial virgin lubricating oil properties.
Trace elements balance in a refinery
Authors: Koncsag Claudia Irina , Dumitru Anca Iuliana
Published: April 2013

The trace elements balance is performed whenever the refinery processes a new type of oil. The goal of the balance is to find the distribution of the trace elements in the products and residues for the market. Also, the balance can warn about the accumulation of metals in the catalysts, this affecting their activity in time. This work presents the case study of a refinery processing a light and sulphurous oil with a medium concentration of trace elements. The study highlighted the following: the highest levels of concentration in feed and products are for Na and Si; in general, trace elements concentrate in heavier factions and residues and especially in the coke as a product or as deposited on calaysts; following the balance, heavy metals concentrate in the coke deposit on FCC catalyst in range of 53% for V to 83% for As; heavy metals concentrate in the gasoline hydrotreating catalyst in range of 7% for Ni to 87% for V.

Published: April 2013

The Tivulaghju megalithic site as been known for a long time. An excavation campaign was directed in 1960 by Roger Grosjean and Jean Liégeois. The chronology of Corsican megalithism was based on the megalithic cists identified there, together with those at Vasculacciu. They were then attributed to the third millennium bc. Revision of the documentation and new data now allow those burial places to be dated to the Middle Neolithic,

i. e. the mid-fifth millennium. Comparable monuments are numerous, in both Corsica and Sardinia; they permit a cultural relationship between those two islands during the Neolithic to be confirmed.
Le Badegoulien de la moitié nord de la France. Un état des connaissances
Authors: Bodu Pierre , Chehmana Lucie , Debout Grégory
Published: April 2013

Dans le Bassin parisien, le Badegoulien a été identifié pour la première fois il y a 70 ans mais ne reste connu qu’au travers d’un nombre limité de sites. Grâce à la fouille de deux gisements clés, le Bois des Beauregards (Seine-et-Marne) et l’abri Fritsch (Indre), certains pans de sa culture matérielle ont pu être décrits dès les années soixante-dix - quatre-vingt. Il aura néanmoins fallu attendre les récentes fouilles réalisées sur le site de Oisy (Nièvre) à partir des années 2000 pour que de nouvelles découvertes viennent enrichir la connaissance de cette période. Exploré depuis cinq ans, ce site fournit en effet une importante documentation qui complète amplement celle recueillie jusqu’à présent. Les analyses actuelles qui visent une meilleure caractérisation technologique des méthodes de fabrication des outils et des armatures en silex y ont d’ores et déjà montré quelques caractères inédits qui ouvrent la voie à de nouvelles discussions. La mise en évidence de ces particularités nous a par ailleurs conduit à effectuer des observations supplémentaires sur le matériel des deux autres gisements principaux, mais aussi sur plusieurs industries régionales présumées badegouliennes. Ainsi, vingt ans après la dernière publication majeure sur le sujet, il est désormais possible de dresser une nouvelle synthèse des connaissances sur le peuplement badegoulien de la moitié nord de la France et d’évoquer les problématiques qui devront être prochainement développées.
Des identités qui se cherchent... Apports des industries lithiques à la question de forigine du Magdalénien moyen dans le Sud-Ouest européen
Authors: Langlais Mathieu
Published: April 2013

En Europe du Sud-Ouest, l’étude comparative des productions lithiques de la fin du Pléniglaciaire participe à la caractérisation de différentes identités, à la fois chronologiques, techno-économiques et territoriales. Plus précisément, ce travail apporte des données concernant la transition du Magdalénien inférieur au Magdalénien moyen dans cette région. L’examen de séquences stratigraphiques telles que Saint-Germain-la-Rivière (Gironde, France), Gandil (Tarn-et-Garonne, France) ou Ekain VII (Pays basque, Espagne) permet de mieux cerner l’apparente variabilité des faciès du Magdalénien inférieur et de réfléchir au processus de «magdalénisation» à travers différents scénarios. À l’orée du Tardiglaciaire, les contrastes techniques et économiques inscrits dans les équipements lithiques impliquent des changements dans les systèmes de production et la mobilité des groupes humains.
Capdenac-le-Haut (Lot) : le Néolithique moyen quercinois stratifié
Authors: Gernigon Karim , Clottes Jean , Carrière Michel , Giraud Jean-Pierre
Published: April 2013

Le site de Capdenac-le-Haut (Lot) est placé sous un éperon dominant la vallée du Lot. La fouille du gisement a mis en évidence une séquence stratigraphique, composée de deux couches superposées, toutes deux datées du Néolithique moyen. Un travail de recollage des tessons de céramique a permis une analyse taphonomique de la dynamique des dépôts et une restitution des niveaux d’accumulation. Trois principaux niveaux ont pu être distingués, celui du sommet pouvant même être subdivisé en six horizons. La séquence ainsi obtenue permet de reconnaître une évolution marquée du style des productions céramiques. Quatre étapes documentent la mise en place progressive des caractères chasséens (formes carénées, prises multiforées, décor rayé-quadrillé) et leur évolution. Lors de l’étape initiale, le répertoire est constitué de récipients non décorés aux formes peu segmentées. Les prises multiforées sont déjà présentes. Dans un second temps, les carènes vives, ainsi que les premiers décors, de type rayé-quadrillé, font leur apparition. Ces caractéristiques marquent encore l’étape suivante, mieux documentée et qui montre la coexistence des coupes à sillon et des assiettes décorées. La dernière étape, qui est antérieure à la fin du Néolithique moyen, présente une simplification des décors et un changement net de la morphologie des écuelles carénées. Cette séquence montre l’importance de la variabilité chronologique du style céramique au cours du Néolithique moyen, ce qui laisse espérer, à terme, une périodisation fine du Chasséen méridional.

Résumé : Les figures (têtes isolées, roues, disques, suidés) représentées sur les stèles capouanes nommées iuvilas dénotent la croyance dans la régénération, dans l'immortalité de l'âme. Cette constatation permet d'interpréter les termes de calendrier contenus dans les inscriptions d'une façon plus précise et plus solide. *Loisarios serait le « dernier » mois de l'année, pumperias « processions », sullemnas « à périodicité annuelle ». Les pumperias sullemnas (ides de mars) semblent équivaloir à la fête d'Anna Perenna et les pumperias falenias au rite des Argées romains. Enfin les vesullias pourraient être un epulum comme les dam(u)sennias.

Résumé : Pour conserver à la légende des origines sa dimension fondatrice, les Romains l'ont périodiquement "actualisée" et réécrite, à l'image du présent. Les guerres civiles de la fin de la République les ont conduits à renforcer la rivalité gémellaire mythique, qu'ils ont ancrée topographiquement : au Palatin de Romulus a été opposé l'Aventin de Rémus, lieu d'une fondation manquée. Le retour de la paix sous le Principat a entraîné la réconciliation des frères ennemis : c'est à ce moment que symboliquement, Rémus a été déplacé sur le Palatin de Romulus, aux côtés duquel il a alors non seulement habité, mais aussi régné.

On souligne aussi les éléments d'originalité méthodologique, comme une heureuse coexistence entre perspectives structurelles et génétiques, avec une place d'honneur pour l'héritage indo-européen et un bon usage des etymologies. Pour finir, le livre est placé dans un cadre de recherche plus large, qu'on pourrait appeler « topologie comparée ».

Un examen approfondi montre que, s'il y a peu de coïncidences lexicales entre les deux oeuvres qui nous restent, celles-ci sont toujours significatives et attestent qu'il existe des proximités conceptuelles : les contraires comme élément moteur, l'importance de la vitesse dans l'action et le caractère ininterrompu du mouvement. Enfin les deux auteurs accordent la prééminence à l'esprit, selon une optique évidemment différente : pour Anaxagore, le « Nous » ou « Intellect » est le principe impassible et sans mélange qui est à l'origine du mouvement et de l'ordre des choses ; pour Thucydide, la notion de « gnome » ou intelligence prévisionnelle, faculté de juger ce qui convient pour le bien de la cité au bon moment, est le propre du chef accompli, dont le modèle est Périclès. Même si l'œuvre de Thucydide est plutôt rapprochée de celle des sophistes, le rôle dévolu à l'intelligence ainsi que la dialectique entre temps et action permettent de penser que le philosophe ionien a eu une influence - impossible à établir avec certitude - sur l'historien.
La construction idéologique du passé agrigentin : Théron et les ossements de Minos

Maria Cruz Cardete del Olmo, The ideological construction of the Agrigentine past: Theron and the bones of Minos, DHA 34/1, 1008, 9-16.

Abstract: In Agrigentum, borders function as areas of constant interaction : separating the Greeks from the indigenous populations and the Greeks from the other Greeks, they concur to set relations between them. Their significance legitimates the instrumentalization of beliefs as ideological justification of the territorial occupation. The mythical construction of the Agrigentum's past elaborated by Theron by means of the return of Minos' bones is taken as an example.
Conón entre Persia y Atenas (394-391 a.C.)

César Fornis, Conon entre la Perse et Athènes (394-391 avant J.-C), DHA 34/2, 2008, 33-64.

Résumé : Il s'agit d'envisager les activités politiques et militaires de Conon depuis la victoire de Cnide (394) jusqu'à sa mort (391). Bien qu'à l'époque de la guerre de Corinthe Conon continua d'être amiral de la flotte perse de l'Egée, et au service du Grand Roi, ceci ne l'empêcha pas d'exercer une influence importante sur la politique athénienne, pour laquelle il conçut un projet mal dessiné de reconstruction impériale, mais qui sera repris sur de nouvelles bases par Thrasybule d'Istrie.
Banques et assurances : cohabitation, mariage ou fusion ?
Authors: Kessler Denis
Published: April 2013

Banking and Insurance

The crisis has brought with it modifications in the economic sociological environments, in behavior and technology, which have led to a rapprochement between banks and insurance companies. Quantitatively, demand has evolved in favor of insurance companies; qualitatively, it has moved away from financial products to financial services and in the process has blurred traditional distinctions. In the face of this evolution the two sectors are condemned to expend great effort in modernization and adaptation. In order to achieve this each possesses certain comparative advantages. An analysis of respective advantages shows that a rapprochement between banks and insurance companies is probable. Other factors, most notably those that are international in nature, lead one to believe that regulatory obstacles which are presently inhibiting a coming together will eventually fade away. Furthermore, in the new deal of the cards between bankers and insurers certain other parties (business, distributors, the state) have joined the game. Thus, the advent of a single sector of financial services within the next decade appears as a plausible future scenario.
Les enjeux des politiques monétaires dans les pays en développement
Authors: Guillaumont Patrick , Guillaumont Sylviane
Published: April 2013

Le présent article étudie d'abord pourquoi une politique de stabilité monétaire facilite la mobilisation des ressources internes en vue du développement. Pour ce faire, il se situe dans deux grands débats théoriques actuels, relatifs aux effets que la hausse du niveau général des prix exerce sur le taux global d'épargne, soit à travers la répartition des revenus (théorie de l'épargne forcée), soit à travers la rémunération de l'épargne (théorie de la répression financière) ; il est ainsi conduit à dénoncer les illusions de l'épargne forcée et les méfaits de l'inflation sur l'épargne volontaire. L'article analyse ensuite quelle politique monétaire favorise une gestion efficace de l'économie. Il indique ainsi les avantages, mais aussi les risques, de la sélectivité du crédit, et le rôle spécifique que les banques centrales des pays en voie de développement sont tenues de jouer dans la surveillance des banques commerciales. Il montre enfin comment une politique monétaire inflationniste, considérée par certains économistes comme le moyen de modifier efficacement la structure interne des prix, est le plus souvent un facteur de déformation des prix relatifs et d'incertitude conduisant à un investissement moindre et mal orienté.
La signification industrielle de la mutation financière
Authors: Gönenç Rauf
Published: April 2013

Les transformations financières des années quatre-vingt ont affecté de manière importante le secteur des entreprises et en particulier leurs comportements d'investissement. Leur coût du capital se détermine désormais dans des marchés financiers déréglementés et plus concurrentiels, et l'utilisation de nouveaux instruments de financement rend leur structure de capital plus flexible — mais aussi plus instable. La substitution des titres de crédit émis sur un grand marché aux crédits bancaires bilatéraux engendre des relations plus distantes et une information plus standardisée entre entreprises et créditeurs. Cela facilite les comportements de désengagement (de « sortie ») et une plus grande rotation des investisseurs dans les entreprises. En même temps, le développement de nouvelles compétences, de nouveaux métiers, et de nouvelles capacités d'investissement dans le secteur d'intermédiation financière favorise des mécanismes d'information plus approfondie et des relations de partenariat actif (de « voix ») entre les entreprises et certains de leurs investisseurs/créditeurs.
Développement du crédit à la consommation et économie réelle

Consumer credit development and real economy

The amplitude of the recent rise in consumption loans renders the evaluation of their impact on household crucial. Accelerations of credit outstanding had already been observed. But a rise of such a magnitude in the variations, which are the net additionnal household resources, has never occured. The chronology of specific credit ceiling tends to show that, up until now, households have been constrained in their demand for loans. Therefore they have borrowed as much as banks have been disposed, to lend. Thus, households which have seen their resources grow more rapidly than their income, have increased their consumption. This fact has resulted in a lowering in the saving ratio. The slow down in the credit outstanding, observed in 1987, provoked a narro-

The prudential control of market risks borne by credit institutions

Market operations made by credit institutions and investment houses have increased significantly over the last decade. The banks and banking system's risk exposure due to these operations should be carefully monitored by an international, European, and therefore French legal framework. After the assessment and coverage by shareholders' equity of both third parties and debtors' default risks (credit risks), borne by credit rating it was, in fact, obvious that a regulation was to be implemented to deal with market risks. Today, it is done through the enforcement of the Directive on shareholders' equity adequacy to market risks.

This article aims at presenting the general principles on which this new regulation is based on (1), describing the risks covered and methods to use (2), in order to present the calculation of the global coverage ratio which has been obtained (3).
Les investisseurs institutionnels étrangers : vers la fin du capitalisme à la française ?

The foreign institutional investors : The end of the french capitalism traditional organisation ?

The first objective of the crossed shareholding system in the French capitalism organisation was to ensure the large groups of firms a stable shareholding and consequently to protect them from foreign investors. This contribution demonstrates that this kind of interfirms relations organisation is today collapsing because of the huge implementation of foreign institutional investors, especially the Anglo-Saxon pension funds, in the capital of the main firms of the CAC 40. This article points out that the application of the corporate governance principles as well as the financial valorization strategies of these pension funds are in complete opposition with the traditional French capitalism organisation.
Pour une politique prudentielle européenne
Authors: Aglietta Michel , Scialom Laurence , Sessin Thierry
Published: April 2013

Les marchés financiers s’intègrent de plus en plus vite après l’euro. Les intermédiaires s’adaptent à cet espace financier par des fusions et acquisitions pour résister à une concurrence exacerbée. La fin de la protection des banques nationales et la montée en puissance de la finance de marché transforment la gestion des risques. L’interdépendance des risques de crédit et de marché pose des problèmes de régulation prudentielle, tant au niveau des établissements que du système financier intégré dans l’espace monétaire de l’euro. Or le traité de Maastricht, négocié sur la base du modèle allemand qui prévalait avant l’intégration financière, a conservé la séparation des dispositifs nationaux disparates de contrôle prudentiel et a grossièrement sous-estimé le risque systémique à la dimension de l’UEM. Un débat animé s’est noué sur les carences prudentielles en Europe. Le présent article s’y inscrit en proposant des axes de réforme pour le contrôle prudentiel des établissements de crédit et pour la maîtrise du risque systémique.

Pour une autorité de supervision financière européenne
Authors: Couppey-Soubeyran Jézabel , Sessin Thierry
Published: April 2013

Dressant un état des lieux des systèmes de supervision européens, organisés sur des modèles différents dont ils proposent une typologie, ils décrivent l’hétérogénéité et la complexité des dispositifs prudentiels nationaux actuels. Ils font ressortir, par ailleurs, les failles d’une telle organisation éclatée face aux conglomérats financiers, aux opérations transfrontières et à la gestion du risque systémique. Ils émettent des doutes quant à l’efficacité du dispositif européen en vigueur, fondé sur le couple formé par la décentralisation du contrôle et l’harmonisation des règles, pour traiter les crises bancaires majeures. Ils plaident pour une réforme structurelle profonde visant à la constitution d’une instance de supervision unique pour l’ensemble des intermédiaires bancaires et financiers, aboutissant à la mise en place d’un méta-niveau de supervision.
La titrisation des risques d’assurance : le marché des "Insurance Linked Securities" (ILS)
Authors: Scherer Alexandre
Published: April 2013

La titrisation des risques d'assurance est un marché de quelques années actuellement en pleine croissance. La technique utilisée consiste à reconditionner des risques d'assurance sous forme de titres négociables de type obligataire. En raison de la nature des risques, ces titres permettent de diversifier un portefeuille d'investissements et d'en améliorer le rapport performance/risque. Il s'agit d'un outil moderne et complémentaire à l'assurance qui devrait permettre d'apporter plus d'efficacité au niveau mondial, notamment dans le domaine des risques de catastrophes naturelles.

Vers un nouveau schéma de réglementation prudentielle : une contribution au débat
Authors: Couppey Jezabel
Published: April 2013

Towards a new scheme of prudential regulation : a contribution to the debate

This article presents a new scheme of prudential regulation with three characteristics, which could lead regulation towards improved efficiency. First, this scheme is three-fold, because it combines regulation, internal control and market discipline. The regulation starts with « pre-commitment » and imposes a solvency rule in the case of a regulated agent defection. The pre-commitment allows for the integration of the internal control ; market discipline is provided by a public disclosure constraint concerning the institution’s solvability. Second, it is dynamic because it takes into account, period by period, the regulator and regulated agents’ reactions. Third, it is global since it is intended to be applied to all regulated financial intermediaries (banking institutions, investment enterprises and insurance companies).

Indices et performances boursières dans l’investissement éthique
Authors: Berthon Jean
Published: April 2013

Cet article aborde la question de l’investissement éthique, et plus particulièrement les fonds éthiques, qui s’imposent une contrainte (morale, environnementale...) dans le choix de leurs placements. Ces fonds, dont les premiers furent créés au début du siècle, commencent à se répandre. Mais l’existence de contrainte dans la sélection des titres pourrait influencer la performance du fonds. En règle générale, les fonds éthiques procèdent tout d’abord à une sélection de titres sur critères financiers, puis dans un second temps, procèdent à une sélection selon des critères « moraux ». Il semble que cette méthode n’ait pas d’impact négatif sur la performance.
Le système bancaire britannique : spécificité et mutations
Authors: Lagoutte Christine
Published: April 2013

British banking system : specificity and evolution

The British banking system is different from the other European systems because of its international size, the concentration of many foreign banks in London, the importance of the City, the reputation and the competitivity of its banks. The historical distinction between Clearing Banks, Merchant Banks and Building Societies is more and more confuse because of their mixed activities in an extreme competitive environment. However main characteristics are emerging which show a division between large international activities in specific areas and the growing part of insurance activities, fund management and mortgage lending on the domestic and European market. The reputation and the profitability of the banking system are not affected by the special UK’s position still outside the euro zone.
