Les Stratégies des Firmes Multinationales Automobiles dans les Villes de l'Élargissement Européen: Réseaux Urbains et Organisation en Chaîne Globale de Valeur

L'Europe centrale fait à la fois figure d'interface et de plateforme sur le continent européen dans des jeux politiques et économiques. L'adhésion à l'Union européenne est porteuse d'espoir en termes de développement de territoires encore marqués par près de 50 ans de régime socialiste. L'intégration de ces territoires à la mondialisation a été insufflée avant tout par des acteurs économiques privés, les firmes multinationales, dès le milieu des années 1990. Par leurs capacités d'investissements et leurs organisations en réseaux à l'échelle mondiale, ces firmes multinationales participent majoritairement à ce processus d'intégration qui repose donc avant tout sur des raisons opportunistes et rationnelles. Les firmes multinationales ont positionné ces territoires dans les activités les plus profitables à l'organisation de leur « chaîne globale de valeur » mondiale. On peut dès lors s'interroger sur l'ampleur et les formes d'intégrations à la mondialisation qu'apportent ces implantations d'entreprises multinationales en particulier pour les villes d'Europe centrale. Dans une approche d'analyse empirique multi-niveaux, la thèse replace les villes d'Europe centrale dans la compétition mondiale des firmes multinationales du secteur automobile qui a particulièrement participé à l'intégration de ces territoires dans des stratégies industrielles mondiales. A un niveau micro, nous analysons les stratégies des firmes automobiles par leurs réseaux d'organisation financière dans une approche à la fois gestionnaire et quantitative. A un niveau méso/macro, nous positionnons les villes d'Europe centrale dans les systèmes de villes européen et mondiaux, selon le rôle attribué dans les chaînes globales de valeur. À chaque étape de cette recherche, l'analyse prend en compte différentes échelles spatiales (urbaine, régionale, nationale, continentale) et plusieurs niveaux d'analyse (micro : les réseaux individuels d'entreprises, méso : les liens intra-urbains, macro : les attractivités interurbaines) afin de souligner les interactions multi échelles qui intègrent chaque espace considéré. Cela nous permet d'évaluer en particulier la place des relations de l'ex-UE15 avec l'Europe centrale dans le contexte des réseaux mondiaux. Les formes transnationales des réseaux des entreprises multinationales, se déployant dans un système de lieux identifiés (métropoles ou villes) sont replacées dans les logiques internationales d'accords bilatéraux, de réglementations régionales et de politiques d'attraction (comme fiscales) ou de soutien au développement (aides nationales ou européennes). L'approche empirique multi échelles, articule les différentes dimensions des stratégies de localisation des entreprises déployées dans leur approche du développement et de la stabilisation de leur chaine globale de valeur, avec les positions relatives des territoires et villes à différents niveaux d'intégration. Ainsi la thèse offre une vision originale de l'articulation des développements locaux des territoires face aux stratégies globales des entreprises.

Cooperation in R&D, firm size and type of partnership: Evidence for the Spanish automotive industry

This paper aims to analyse cooperation in R&D in the automobile industry in Spain. It first examines to what extent firms cooperate with external actors in the field of technological innovation, and if so, with what type of cooperation partner, paying special attention to the differentiation according to the size of the firms. Second, it aims to study how the firm’s size may affect not only the decision of cooperating but also with which type of partner, while controlling for other determinants that have been considered in the literature as main drivers of collaborative activities in R&D. We use data provided by the Technological Innovation Panel in the 2006-2008 period for firms in the automotive sector. We estimate a bivariate probit model that takes into account the two types of cooperation mostly present in the automotive industry, vertical and institutional, explicitly considering the interdependencies that may arise in the simultaneous choice of both.

Modelling the disability severity score in motor insurance claims: an application to the Spanish case

Bodily injury claims have the greatest impact on the claim costs of motor insurance companies. The disability severity of motor claims is assessed in numerous European countries by means of score systems. In this paper a zero inflated generalized Poisson regression model is implemented to estimate the disability severity score of victims in-volved in motor accidents on Spanish roads. We show that the injury severity estimates may be automatically converted into financial terms by insurers at any point of the claim handling process. As such, the methodology described may be used by motor insurers operating in the Spanish market to monitor the size of bodily injury claims. By using insurance data, various applications are presented in which the score estimate of disability severity is of value to insurers, either for computing the claim compensation or for claim reserve purposes.

Tecnologia de células a combustível

The fuel cell principle was discovered by Sir Grove 150 years ago. However material problems prohibited its commercialization for a long time. A change has been occurring during the last 30 years, so two types of fuel cell technologies can be distinguished: low and high temperature operation cells. Nowadays, only phosphoric acid cells are commercially offered as 200 kWel power plants. Membrane cells are more suitable for automobile electrotraction with a very low (or no) environmental impact. The fuel continues, however, to play a very particular role, since hydrogen is not easy to store and to transport. The more promising target is the utilization of liquid methanol. The Brazilian scenario concerning this kind of technology is discussed.

Células a combustível de baixa potência para aplicações estacionárias

A paradigmatic shift in developing fuel cell for stationary applications has been occurring in the last ten years. Previously, 100 kW class to a few MW class power plants were preferred but recently, the development has drifted towards units of only a few kW. The motivation is the present market situation, which favors disperse residential electric power generation from natural or liquefied gas. Membrane-type fuel cells are very promising for this application, due to their present state of development in the automobile industry. More recently, small ceramic fuel cells (SOFC) has also been found to be adequate for this application. Considering a family of 4 members, 1 kW (electric) units seem to be optimal for individual residences. This presentation discusses briefly the Brazilian scenario with respect to these units.

Determinants of the decision to appeal against motor bodily injury settlements awarded by Spanish trial courts

Automobile bodily injury disputes represent one of the main causes of litigation faced by Spanish Courts. In this paper a multinomial model is implemented to analyse which factors determine the decision to appeal against the verdicts of trial courts. Use of a dataset of motor insurance claims revealed differences between the determinants of a claimant’s decision to appeal and those of insurers. Among other results it is shown that discrepancies regarding the permanent disability sustained affect the insurer’s decision to appeal. In contrast, the claimant pays more attention to differences in the stated temporary disability. Conclusions are drawn regarding which factors could reduce the percentage of appealed cases.

A gestão do conhecimento aplicada à reciclagem de componentes automotivos através do tratamento das informações contidas em documentos de patentes

This article evaluates the technologies adopted for recycling and reuse of automobile components, through the analysis of patents documents. The automobile batteries recycling is the main topic, followed by the automatic disassembly of vehicles, tires recycling and polyurethane recycling. None document approached recycling of steel and aluminum or ceramics products. The reduced number of technologies for the recycling of the polymeric compounds (including polyurethane) indicates that a bigger number of research and inventions must be elaborated in the next years, aiming at to the reduction of costs of processes and adequacy to the more restricted environmental legislation.

1,3-propanodiol: produção, aplicações e potencial biotecnológico

1,3-propanediol is a high-value specialty chemical which has many industrial applications. Its main use is the production of the polymer polypropylene terephthalate, a thermoplastic used in the textile and automobile industries. The interest in 1,3-propanediol production from glycerol bio-conversion has increased after the employment of biodiesel by various countries, being produced by chemical synthesis from petroleum intermediates or biotechnologically by microbial fermentation. Glycerol is an abundant low-cost byproduct from biodiesel refineries, and it is the only substrate that can be naturally or enzymatically converted to 1,3-propanediol by microbial fermentation. In this review, information on 1,3-propanediol's importance, production and purification are presented, along with results from recent research on glycerol microbial conversion to 1,3-propanediol. The bio-production of this intermediate compound from glycerol is very attractive both economically and environmentally, since it allows the replacement of fossil fuels by renewable resources.

Comparative anatomical study of the leg's nerves of Cebus (barbed capuchins) with baboons, chimpanzees and modern humans

The anatomical comparative studies among the primates are important for the investigation of ethology, evolution, taxonomy, and comprehension of tools by hominoids. Especially the anatomical knowledge of Cebus contributes to conservation of the species, and to development of surgical procedures and clinical treatments of these animals, as they frequently are victims of automobile accidents. Recent anatomical studies came to a wrong conclusion regarding behavioral traits of Cebus, ascribed to few data available in previous literature. Therefore, to provide anatomical data and to support the other sciences related to anatomy, and to develop surgical and/or clinical procedures, we described the nerves of the legs of Cebus foccusing on their position and trajectory, as wll as innerved muscles, and compared these results with those of humans and other primates. Eight adult capuchin specimens were used for this study. The anatomical comparative study of the leg's nerves of Cebus demonstrated that, in general, structural organization of the nerves is similar among the four primates analyzed here (Cebus, chimpanzees, baboons and humans), which might be attributed to the fact that the all four primates have similar body structures. However, nerve trajectory and muscles innervation in Cebus was more similar to baboons.

Effect of particle morphology on the mechanical and thermo-mechanical behavior of polymer composites

Fiber reinforced polymer composites have been used in many applications, such as in automobile, aerospace and naval industries, due basically to their high strength-to-weight and modulus-to-weight, among other properties. Even though particles are usually not able to lead to the level of reinforcement of fibers, particle reinforced polymer composites have been proposed for many new applications due to their low cost, easy fabrication and isotropic properties. In this work, polymer composites were prepared by incorporating glass particles of different morphologies on poly(aryl sulfones) matrices. Particles with aspect ratios equal to 1, 2.5 and 10 were used. The prepared composites were characterized using electron microscopy and thermal analysis. Mechanical properties of the composites were evaluated using a four-point bending test. The thermo-mechanical behavior of the obtained composites was also investigated. The results showed that the morphology of the particles alter significantly the mechanical properties of composites. Particles with larger values of aspect ratio led to large elastic modulus but low levels of strain at failure. This result was explained by modeling the thermo-mechanical behavior of the composites using a viscoelastic model. Parameters of the model, obtained from a Cole-Cole type of plot, demonstrated that interactions at the polymer-reinforcing agent interface were higher for composites with large aspect ratio particles. Higher levels of interactions at interfaces can lead to higher degrees of stress transfer and, consequently, to composites with large elastic modulus, as experimentally observed.

Vauhtikausi. Autoilun sukupuoli 1920-luvun Suomessa

The Age of Speed:Automobility’s Gender in the 1920s Finland The aim of this study is to analyze the connections between automobility and gender in Finland in the 1920s. In this study it is argued that the 1920s was the significant era in the Finnish history of automobility when many of the long-lasting gendered notions and cultural understandings were constructed. This study combines cultural history of technology with gender analysis. As the previous research on gender and technology has recognized, technology is a significant site of gender negotiations. Both from the cultural historical perspective and a gender perspective it is important to understand both technology and gender as cultural constructions. They were linked together and constructed each other. In other words: technology shapes gender and gender shapes technology. Historians of technology like Nina Lerman, Ruth Oldenziel and Arwen Mohun have argued that both gender and technology are about power: social, cultural, economic and political. In this study automobility means technology that can be analyzed in layers of identity, structures, institutions and representations. The source material consists of various types of historical sources, magazines and journals, advertisements, archival material together with films and literature. In the previous studies of the history of automobility gender has often been neglected. The term “gender” has also quite often been misunderstood. Some studies in the field have only focused on the early female drivers. However, far too little attention has been paid to the question, why automobility was considered as masculine sphere only. This study aims to give new insights to the previous interpretations of the history of automobility. As in various other countries also in Finland, the decade of the 1920s is characterized as a period of “modern times.” It was also the era of the automobiles. Although the number of cars in Finland was still low compared to the other European countries and the USA, in press, films and literature, images of automobiles and new women – and men – on the wheel became as an emblem of a new era. The thesis consists of three main chapters. The first main chapter focuses on the conflicts between drivers and non-drivers. The study shows how in the debate of the automobility “a driver” was constantly referred as a man and “a pedestrian” accordingly a woman, even though in the reality there were as much men and women walking on the streets and the roads. Thus, the public debate constructed and reconstructed the gendered traffic system where men were playing the key role. The second main chapter of the study analyses the automobile clubs and the cultural representations. The chapter answers the question how the concept of a driver was gendered. The Automobile clubs and the organizations of professional drivers were in a significant role in developing the early history of traffic in Finland. The Finnish Automobile Club (Suomen Automobiili Klubi, founded in 1919) was the oldest and the most powerful of all automobile organizations. The Finnish Automobile Club accepted women as members from the very beginning. The membership was strictly limited to the upper class and the very first female members were wives and daughters of the male members. However, Doctor of medicine and surgery 316 Karolina Eskelin (1867-1936) the founding member of the Club was an exception to that convention. The male members of the Finnish Automobile Club attended official international meetings and consulted Finnish authorities in traffic and road questions, whereas, female members joined car trips, picnics and social gatherings arranged by the club. Few young female members of the club drove in races and gross-country-tours. The cultural representations of drivers in the Finnish media in the 1920s both deconstructed and reconstructed the concept of gender. In Finnish press in general, motoring was seen as male dominated area. Men were represented as the experts of the automobility. The drivers’ uniforms and the automobile clubs underlined professionalism and expertise which, thus, got masculine meaning. Women were beautiful accessories in the car ads, but they were also becoming a new consumer group in the market. The representations of the female and the male drivers influenced and shaped actively the understandings of femininity and masculinity. In the third main chapter the analysis focuses on the automobile as an artifact.The automobile was considered as an artifact that primarily belonged to the masculine domain. However, the representations of the automobiles were ambivalent. The automobile was both masculine and feminine depending on the context. The representations of the automobile were also used to construct the discourse of heteronormativity.

Arduino-pohjainen OBD2-lukija SAE J1850 VPW protokollatuella

Kandidaatintyössä toteutetaan OBD2 (On-Board Diagnostics 2) -lukija ajoneuvon päästöjenhallintajärjestelmän diagnostiikkatiedoille yleiskäyttöisellä mikro-ohjaimella. Lukija tukee tiedonsiirtoprotokollana SAE J1850 VPW protokollaa. Mikro-ohjaimena on Atmel Corporationin AVR ATMega328. Työn tavoitteena on havainnoida vastaantulevia käytännön ongelmia ja haasteita mikro-ohjaimen käytöllä tiedonsiirtoprotokollan toteutukseen, ja verrata toteutettua järjestelmää kaupallisiin OBD2-lukijoihin. Työn johtopäätöksenä havaitaan mikro-ohjaimen suorituskyvyn rajoitteet ja sen tuomat toiminnan epävarmuustekijät. Työssä myös todetaan, että mikro-ohjain soveltuu tiedonsiirtoprotokollan toteutukseen kun rajoitteet otetaan huomioon. Kaupallisiin lukijoihin verrattuna yleiskäyttöiseen mikro-ohjaimeen perustuva toteutettu järjestelmä on kalliimpi ja toiminnoiltaan suppeampi. Mikro-ohjaimeen perustuva järjestelmä on kuitenkin muokattavissa ja laajennettavissa tarvittaessa, jolloin toteutukseen voidaan saada kaupallisista järjestelmistä mahdollisesti puuttuvia ominaisuuksia, kuten valmistajakohtaisia protokollia ja toimintoja, joita ei ole määritelty OBD2:ssa. Yhtenä esimerkkinä tällaisesta toiminnosta voi mainita ajoneuvoissa yleistyvän sähköisen käsijarrun säätöä ohjaavat komennot jarruhuoltoa varten.
