The Rationality of Revolution.

Did the recent transition to liberal democracy in Eastern Europe consitute revolutions? Here, game theory is used to structure an explanation of institutional change proposed by Harold Innis (1950).

The household revolution: childcare, housework, and female labor force participation

Over the twentieth century, the allocation of womens' time changed dramatically. This paper explores the implications for the allocation of married womens' time stemming from: (1) the household revolution associated with the introduction of a variety of labor-saving devices in the home; (2) the remarkable increase in the relative wage of women; and (3) changes in childcare requirements associated with changes in fertility patterns. To do so, we construct a life-cycle model with home production and childcare constraints. The parameters of the childcare production function are estimated using micro evidence from U.S. time use data. We find that the increase in the relative wage of women is the most important explanation of the increase in married womens' market work time over the twentieth century. Changes in fertility had large effects up to 1980, but little effect thereafter. The declining price of durables has an appreciable effect only since 1980, an effect that is consistent with a broader interpretation of durable goods reflecting the marketization of home production.

Sign, meaning and violence in Laurell K. Hamilton’s novels : a postmodernist approach

La nature iconoclaste de l'ère postmoderne se manifeste dans une révolution contre les normes littéraires préétablies. Cet iconoclasme est plus flagrant dans la fantaisie urbaine. Dans un environnement désordonné, fragmenté et très stéréotypé, la fantaisie urbaine est considérée comme un événement qui défie tout jugement, et toute stratification sociale. Bien qu'elle ait été bien accueillie par les lecteurs et qu'elle a obtenue de fortes ventes, c'est seulement depuis deux décennies que ces genres ont commencé à attirer l'attention académique. Ce travail peut être considéré comme une tentative pour comprendre la fantaisie urbaine à travers la série d'une de ses écrivains les plus éminents, Laurell K. Hamilton. En conséquence, j’ai choisi trois romans de sa série Anita Blake: Guilty Pleasures (1993), Circus of the Damned (1995) et Blue Moon (1998). Les paramètres stylistiques et thématiques dans ses romans créent une philosophie postmoderne de subversion, qui valide et invalide les discussions sur la structure du signe, la violence, et la réaction du lecteur. Le premier chapitre étudie la construction du sens à travers la structure de la langue de la fantaisie urbaine. Il traite la signification que le résultat de l'interaction entre les différents signes linguistiques. Il suit également l'évolution de ce que Derrida appelle «inflated signs», qui sont au coeur de la régénération du sens à travers les romans. La saturation dans ces signes implique une «absence» qui s'affiche à travers la désintégration du système de la langue et les ruptures récurrentes de sa structure globale. Le deuxième chapitre se concentre sur les tendances de la violence dans les romans de la fantaisie urbaine qui rendent les jeux de pouvoir des personnages truculents et leurs réactions apparaissent inadmissibles. Il examine la violence par rapport à ses causes et sa ii logique. Grâce aux concepts de Derrida de l’‘arché-violence’, de ‘décision’ et de ‘sacrifice,’ je démontre que la violence est inévitable dans le monde créé de Hamilton et dans le monde qu'elle simule. Le troisième chapitre examine la réaction du lecteur sur les événements exotiques et la caractérisation paranormale des romans de Hamilton. Il révèle comment la fantaisie urbaine conteste la conception de Wolfgang Iser de réaction du lecteur et le concept d'‘apparence’ de Jean Baudrillard. J’insiste sur le fait que les lecteurs de la fantaisie urbaine ne sont plus des interprètes ou des réceptifs passifs d'images paranormaux. En effet, l'interaction entre l’auteur et le lecteur, que ces romans entrainent, défie ces conceptions réductrices de la réaction du lecteur.

Drug-loaded nanocarriers : passive targeting and crossing of biological barriers

Poor bioavailability and poor pharmacokinetic characteristics are some of the leading causes of drug development failure. Therefore, poorly-soluble drugs, fragile proteins or nucleic acid products may benefit from their encapsulation in nanosized vehicles, providing enhanced solubilisation, protection against degradation, and increased access to pathological compartments. A key element for the success of drug-loaded nanocarriers (NC) is their ability to either cross biological barriers themselves or allow loaded drugs to traverse them to achieve optimal pharmacological action at pathological sites. Depending on the mode of administration, NC may have to cross different physiological barriers in their journey towards their target. In this review, the crossing of biological barriers by passive targeting strategies will be presented for intravenous delivery (vascular endothelial lining, particularly for tumour vasculature and blood-brain barrier targeting), oral administration (gastrointestinal lining) and upper airway administration (pulmonary epithelium). For each specific barrier, background information will be provided on the structure and biology of the tissues involved as well as available pathways for nano-objects or loaded drugs (diffusion and convection through fenestration, transcytosis, tight junction crossing, etc.). The determinants of passive targeting − size, shape, surface chemistry, surface patterning of nanovectors − will be discussed in light of current results. Perspectives on each mode of administration will be presented. The focus will be on polymeric nanoparticles and dendrimers although advances in liposome technology will be also reported as they represent the largest body in the drug delivery literature.

Studies on Rubber Composition as Passive Acoustic Materials in Underwater Electro Acoustic Tranducer Technology and Their aging Characteristic

The research work has been in the area of compounding and characterization of rubbers for use in under water electro acoustic transducers. The study also covers specific material system such as encapsulation materials, baffle material, seal material, etc. Life prediction techniques of under water rubbers in general have been established with reference to more than one functional property. Ranges of passive materials, besides the active sensing material go into the construction of underwater electro acoustic transducers. Reliability of the transducer is critically dependent on these passive materials. Rubbers are a major class of passive materials. The present work concentrates on these materials. Conventional rubbers are inadequate to meet many of the stringent function specific requirements. There exists a large gap of information in the rubber technology of underwater rubbers, particularly relating to underwater electro acoustic transducers. This study is towards filling up the gaps of information in this crucial area. Water intake into rubber is considered as the single most important issue for the long-term performance of rubbers, especially Neoprene. In this study, the cause and effects of a range of parameters affecting the water absorption by diffusion and permeation have been investigated.

Design, Fabrication and Characterization of Passive and Active Polymer Photonic Devices

The rapid developments in fields such as fibre optic communication engineering and integrated optical electronics have expanded the interest and have increased the expectations about guided wave optics, in which optical waveguides and optical fibres play a central role. The technology of guided wave photonics now plays a role in generating information (guided-wave sensors) and processing information (spectral analysis, analog-to-digital conversion and other optical communication schemes) in addition to its original application of transmitting information (fibre optic communication). Passive and active polymer devices have generated much research interest recently because of the versatility of the fabrication techniques and the potential applications in two important areas – short distant communication network and special functionality optical devices such as amplifiers, switches and sensors. Polymer optical waveguides and fibres are often designed to have large cores with 10-1000 micrometer diameter to facilitate easy connection and splicing. Large diameter polymer optical fibres being less fragile and vastly easier to work with than glass fibres, are attractive in sensing applications. Sensors using commercial plastic optical fibres are based on ideas already used in silica glass sensors, but exploiting the flexible and cost effective nature of the plastic optical fibre for harsh environments and throw-away sensors. In the field of Photonics, considerable attention is centering on the use of polymer waveguides and fibres, as they have a great potential to create all-optical devices. By attaching organic dyes to the polymer system we can incorporate a variety of optical functions. Organic dye doped polymer waveguides and fibres are potential candidates for solid state gain media. High power and high gain optical amplification in organic dye-doped polymer waveguide amplifier is possible due to extremely large emission cross sections of dyes. Also, an extensive choice of organic dye dopants is possible resulting in amplification covering a wide range in the visible region.

Studies on rubber compositions as passive acoustic materials in underwater electro acoustic transducer technology-and their aging characteristics

Rubber has become an indispensable material in Ocean technology. Rubber components play critical roles such as sealing, damping, environmental protection, electrical insulation etc. in most under water engineering applications. Technology driven innovations in electro acoustic transducers and other sophisticated end uses have enabled quantum jump in the quality and reliability of rubber components. Under water electro acoustic transducers use rubbers as a critical material in their construction. Work in this field has lead to highly reliable and high performance materials which has enhanced service life of transducers to the extent of 1015 years. Present work concentrates on these materials. Conventional rubbers are inadequate to meet many of the stringent functional of the requirements. There exists large gap of information in the rubber technology of under water rubbers, particularly in the context of under water electro acoustic transducers. Present study is towards filling up the gaps of information in this crucial area. The research work has been in the area of compounding and characterisation of rubbers for use in under water electro acoustic transducers. The study also covers specific material system such as encapsulation material, baffle material, seal material, etc. Life prediction techniques of under water rubbers in general has been established with reference to more than one functional property. This thesis is divided into 6 chapters.
