Le rôle des États-Unis dans le maintien des pratiques d’opacité financière

Notre recherche vise à vérifier s'il existe un lien entre l'intérêt des Américains pour les investissements étrangers et le maintien des structures opaques de la finance internationale. Les pratiques d'opacité financière (utilisation abusive du secret bancaire, faibles mesures d'identification du client, faible règlementation bancaire, absence d’échange d’information fiscale, absence d’obligations d’enregistrements de compagnies et de fiducies, possibilité d’établir la propriété d’une société avec des prête-noms, utilisation de bons au porteur, manque d’encadrement des fiducies, etc.) semblent accommoder les États qui les dénoncent. Utilisant les théories des jeux à deux niveaux de Putnam, de la règlementation et de l’équilibre de Nash, nous faisons le lien entre le niveau national et international. Notre recherche consiste en deux études de cas. La première traite d’un projet de règlement de l’Internal Revenue Service visant à assurer la déclaration de revenus d’intérêt sur les dépôts bancaires des non-résidents. La seconde traite d’une série de projets de loi déposés au Sénat et à la Chambre des représentants des États-Unis. Ils cherchent à assurer la transparence du processus d’enregistrement de compagnies de manière à faciliter l’accès des agences d’application de la loi à l’information sur les bénéficiaires effectifs des compagnies formées en sol américain. Notre recherche ne permet pas de confirmer notre hypothèse avec certitude. Cependant, nos données tendent à indiquer que les groupes d’intellectuels et les groupes de pression financiers incitent le gouvernement des États-Unis à freiner la mise en application de certaines mesures prévues par le régime antiblanchiment (particulièrement l’identification du client et le partage d’information avec des pays tiers) pour attirer l’investissement étranger.

L’engagement militant des jeunes dans le contexte du syndicalisme contemporain

La jeune génération de salariés est souvent accusée d’être moins militante, moins solidaire que les générations précédentes. L’objectif général de cette recherche est de démystifier les préjugés entourant l’engagement militant chez les jeunes syndiqués québécois d’aujourd’hui. Pour ce faire, divers concepts sont présentés, comme celui de jeunesse, de génération et d’engagement militant. Une synthèse de l’évolution historique de l’engagement militant ainsi que la situation particulière de la jeunesse contemporaine dans l’action syndicale permettent de dresser un portrait général. Notre cadre théorique repose sur les concepts d’individualisme et de conflit. L’approche qualitative et l’entrevue semi-dirigée ont été privilégiées. Le résultat de notre enquête menée auprès de dix-sept facteurs et factrices du Syndicat des travailleurs et travailleuses des postes nous révèle que l’engagement militant des jeunes est à la fois le reflet d’une distanciation et une manière différente de concevoir l’engagement militant. Les jeunes syndiqués ne sont pas plus individualistes que les autres générations, mais ils connaissent peu le syndicalisme. D’une part, les jeunes adoptent une position de recul afin de mieux s’approprier la chose syndicale. Il est possible d’affirmer que l’engagement militant n’est pas un phénomène statique, il évolue en acquérant l’expérience. D’autre part, faiblement socialisés au syndicalisme et fortement socialisés au droit, au dialogue et au respect, les jeunes syndiqués appréhendent les conduites violentes et les discours martiaux. Ces derniers ont une vision modérée sans être pour autant passive, car ils valorisent l’action collective et ont plus de facilités à déposer des griefs.

2D, 3D and 4D active compound delivery in tissue engineering and regenerative medicine

Recent advances in tissue engineering and regenerative medicine have shown that controlling cells microenvironment during growth is a key element to the development of successful therapeutic system. To achieve such control, researchers have first proposed the use of polymeric scaffolds that were able to support cellular growth and, to a certain extent, favor cell organization and tissue structure. With nowadays availability of a large pool of stem cell lines, such approach has appeared to be rather limited since it does not offer the fine control of the cell micro-environment in space and time (4D). Therefore, researchers are currently focusing their efforts on developing strategies that include active compound delivery systems in order to add a fourth dimension to the design of 3D scaffolds. This review will focus on recent concepts and applications of 2D and 3D techniques that have been used to control the load and release of active compounds used to promote cell differentiation and proliferation in or out of a scaffold. We will first present recent advances in the design of 2D polymeric scaffolds and the different techniques that have been used to deposit molecular cues and cells in a controlled fashion. We will continue presenting the recent advances made in the design of 3D scaffolds based on hydrogels as well as polymeric fibers and we will finish by presenting some of the research avenues that are still to be explored.

Studies on the Dipping Characteristics of RVNRL and NRLatex Compounds

ABSTRACT: The dipping characteristics of radiation-vulcanized natural rubber latex and natural rubber latex compounds were investigated with a lab-model semiautomatic dipping machine. The effect of the variation of the speed of immersion and withdrawal, dwell time, compound viscosity, and concentration of coagulant on the thickness of the latex deposit was investigated. The results of the study show that the deposit thickness depends on the withdrawal speed of the former, the concentration of the coagulant, dwell times, and the viscosity of the latex compounds

Automation of Chemical Spray Pyrolysis Unit and Fabrication of Sprayed CuInS2/In2S3 Solar Cell

Aim of the present work was to automate CSP process, to deposit and characterize CuInS2/In2S3 layers using this system and to fabricate devices using these films.An automated spray system for the deposition of compound semiconductor thin films was designed and developed so as to eliminate the manual labour involved in spraying and facilitate standardization of the method. The system was designed such that parameters like spray rate, movement of spray head, duration of spray, temperature of substrate, pressure of carrier gas and height of the spray head from the substrate could be varied. Using this system, binary, ternary as well as quaternary films could be successfully deposited.The second part of the work deal with deposition and characterization of CuInS2 and In2S3 layers respectively.In the case of CuInS2 absorbers, the effects of different preparation conditions and post deposition treatments on the optoelectronic, morphological and structural properties were investigated. It was observed that preparation conditions and post deposition treatments played crucial role in controlling the properties of the films. The studies in this direction were useful in understanding how the variation in spray parameters tailored the properties of the absorber layer. These results were subsequently made use of in device fabrication process.Effects of copper incorporation in In2S3 films were investigated to find how the diffusion of Cu from CuInS2 to In2S3 will affect the properties at the junction. It was noticed that there was a regular variation in the opto-electronic properties with increase in copper concentration.Devices were fabricated on ITO coated glass using CuInS2 as absorber and In2S3 as buffer layer with silver as the top electrode. Stable devices could be deposited over an area of 0.25 cm2, even though the efficiency obtained was not high. Using manual spray system, we could achieve devices of area 0.01 cm2 only. Thus automation helped in obtaining repeatable results over larger areas than those obtained while using the manual unit. Silver diffusion on the cells before coating the electrodes resulted in better collection of carriers.From this work it was seen CuInS2/In2S3 junction deposited through automated spray process has potential to achieve high efficiencies.

Studies on the foraminifera of the south west coast of india

The present investigations confine to a study of the distribution of foraminifera in the estuarine environment and the interstial area of the sandy beaches of the south west coast of India with a view to correlate the distribution and the intensity of occurrence of the various species with hydrographic conditions and the substrate characteristics of the area. Studies on the foraminifera of the estuarine environment were carried out in the vembanad lake ,a major estuary in the south west coast of india extending for about 60km from cochin barmouth in the north to Alleppey in the south.Fortnightly collections of hydrographical data and grab samples of bottom deposit were made for a period of 2 years (july 1973 to june 1975) from fifteen stations chosen along the length of the lake.

Receivable Management in Non Banking Finance Companies with Special Reference to Vehicle Financing

In the absence of entry barrier or regulatory restrictions, Non Banking Financial Companies frantically grew and accessed the public deposit without any regulatory control. The deposit of NBFCs grew from Rs. 41.9 crore in 1971 to 53116.0 crore in 1997. This growth was the result of a combined effect of increase in the number of NBFCs and increase in the amount of deposits. The deposits amazed as above was invested in various assets especially that in motor vehicles by these asset financing NBFCs. Various tactics were adopted by these NBFCs and their agents for recovering the receivable outstanding from such assets. Both central government and RBI were concerned about the protection of depositors‘ interest and various committees were set up to frame a comprehensive regulation for the functioning of these NBFCs.

Structural, electrical and electrochemical characterization of high frequency magnetron sputtered spinel oxide cathode films for lithium ion battery applications

The main challenges in the deposition of cathode materials in thin film form are the reproduction of stoichiometry close to the bulk material and attaining higher rates of deposition and excellent crystallinity at comparatively lower annealing temperatures. There are several methods available to develop stoichiometric thin film cathode materials including pulsed laser deposition; plasma enhanced chemical vapor deposition, electron beam evaporation, electrostatic spray deposition and RF magnetron sputtering. Among them the most versatile method is the sputtering technique, owing to its suitability for micro-fabricating the thin film batteries directly on chips in any shape or size, and on flexible substrates, with good capacity and cycle life. The main drawback of the conventional sputtering technique using RF frequency of 13.56MHz is its lower rate of deposition, compared to other deposition techniques A typical cathode layer for a thin film battery requires a thickness around one micron. To deposit such thick layers using convention RF sputtering, longer time of deposition is required, since the deposition rate is very low, which is typically 10-20 Å/min. This makes the conventional RF sputtering technique a less viable option for mass production in an economical way. There exists a host of theoretical and experimental evidences and results that higher excitation frequency can be efficiently used to deposit good quality films at higher deposition rates with glow discharge plasma. The effect of frequencies higher than the conventional one (13.56MHz) on the RF magnetron sputtering process has not been subjected to detailed investigations. Attempts have been made in the present work, to sputter deposit spinel oxide cathode films, using high frequency RF excitation source. Most importantly, the major challenge faced by the thin film battery based on the LiMn2O4 cathode material is the poor capacity retention during charge discharge cycling. The major causes for the capacity fading reported in LiMn2O4cathode materials are due to, Jahn-Teller distortion, Mn2+ dissolution into the electrolyte and oxygen loss in cathode material during cycling. The work discussed in this thesis is an attempt on overcoming the above said challenges and developing a high capacity thin film cathode material.

Does it pay to be socially responsible? Evidence from spanish retail banking sector

This paper presents a theoretical and empirical analysis of strategic competition in retail banking when some of the financial firms are non-profit organisations that invest in social activities. Banking literature about competition is fairly large, but the strategic interaction between profit maximizing and non profit maximizers has not been extensively analysed except for Purroy and Salas (1999). In this paper, a completely different approach is taken. An adaptation of Hotelling’s two stage model of spatial competition is developed to take into account consumer perceptions respect to the two different types of financial institutions. The empirical analysis confirms that consumers take into account other features different from the price, such as social contribution or closer service to make a deposit or mortgage decision. These conclusions are of interest in the debate about a firm’s social or ethical activities. It is shown that if consumers value social activities, firms can improv

Mercados interbancarios no colateralizados e información asimétrica: un mecanismo para lograr la participación plena de los bancos deficitarios cuando existen altos niveles y dispersión del riesgo de contraparte

En este trabajo se proponen dos tipos de contratos para los préstamos interbancarios con el fin de que los bancos suavicen sus choques de liquidez a través del mercado interbancario. En particular, se estudia la situación en la que los bancos con faltantes de liquidez que tienen bajo riesgo de crédito abandonan el mercado debido a que la tasa de interés es alta en relación a su fuente alterna de financiamiento. La asimetría en la información acerca del riesgo de crédito impide que los bancos con excedentes de liquidez ajusten la tasa de interés considerando el riesgo de su contraparte. Dado lo anterior, se diseñan dos contratos para los créditos interbancarios que se diferencian en las tasas de interés cobradas. Así, siempre que un banco constituya un depósito podrá obtener liquidez a bajas tasas de interés; en la situación contraria la tasa será más elevada.
