Esta investigação insere-se na temática do Empreendedorismo Imigrante e do Comércio Étnico. Trata-se de uma pesquisa que se debruça sobre a imigração para Cabo Verde, com destaque para a análise da imigração chinesa, sobretudo dedicada ao comércio na ilha de São Vicente. O objectivo geral deste trabalho prende-se com a identificação do contributo da comunidade imigrante supracitada no processo de desenvolvimento de São Vicente, através da instalação e da prática de actividades comerciais. Para concretização deste objectivo foi desenvolvido, durante 5 meses, um trabalho de terreno em Cabo Verde (Santiago e São Vicente). O trabalho empírico socorreu-se de entrevistas formais à presidente da Câmara Municipal de São Vicente e a personalidades da Embaixada de China em Cabo Verde , e informais efectuadas aos comerciantes chineses e seus funcionários, bem como aos comerciantes locais. Foram ainda aplicados inquéritos a todos os comerciantes chineses na ilha de São Vicente, processo que permitiu obter a informação necessária para a caracterização da comunidade chinesa e das actividades comerciais por ela aqui desenvolvidas. Os resultados destes questionários foram armazenados numa base de dados informática, com recurso ao SPSS- Statistical Package for Social Sciences, também utilizado como instrumento de tratamento da informação, assim como a folha de cálculo Excel. Dos resultados da nossa investigação, ressalta que o comércio chinês tem dinamizado muito o tecido comercial sãovicentino, contribuindo para a criação de novos postos de trabalho, diversificando as ofertas e estabilizando ou levando mesmo à redução do preço dos produtos, o que vem generalizar as possibilidades de consumo a segmentos da população menos solventes, que até então tinham muita dificuldade em comprar bens como brinquedos ou certos artigos para o lar. De realçar também que, entre o comércio chinês e o comércio local, existe para além da concorrência como é óbvio, uma certa complementaridade. Esta relação recíproca é estabelecida através de aquisição e revenda de produtos diversificados adquiridos aos comerciantes locas, permitindo assim oferecer assim mais produtos e de melhor qualidade aos seus clientes. Todavia, conclui-se que o comércio chinês, com todas as implicações que trás, ainda não constitui um vector central do desenvolvimento da ilha, designadamente se entendermos o desenvolvimento numa perspectiva abrangente e integral, que incorpora dimensões culturais, sociais e ecológicas que ultrapassam a esfera económica. Contudo, pode-se dizer que a presença do comércio chinês na ilha tem sido bastante positiva, uma vez que coloca no mercado uma diversidade de produtos a preços razoavelmente acessíveis, contribuindo para melhorar a qualidade de vida dos São Vicentinos.

Choosing what to eat is a complex activity for humans. Determining a food's pleasantness requires us to combine information about what is available at a given time with knowledge of the food's palatability, texture, fat content, and other nutritional information. It has been suggested that humans may have an implicit knowledge of a food's fat content based on its appearance; Toepel et al. (Neuroimage 44:967-974, 2009) reported visual-evoked potential modulations after participants viewed images of high-energy, high-fat food (HF), as compared to viewing low-fat food (LF). In the present study, we investigated whether there are any immediate behavioural consequences of these modulations for human performance. HF, LF, or non-food (NF) images were used to exogenously direct participants' attention to either the left or the right. Next, participants made speeded elevation discrimination responses (up vs. down) to visual targets presented either above or below the midline (and at one of three stimulus onset asynchronies: 150, 300, or 450 ms). Participants responded significantly more rapidly following the presentation of a HF image than following the presentation of either LF or NF images, despite the fact that the identity of the images was entirely task-irrelevant. Similar results were found when comparing response speeds following images of high-carbohydrate (HC) food items to low-carbohydrate (LC) food items. These results support the view that people rapidly process (i.e. within a few hundred milliseconds) the fat/carbohydrate/energy value or, perhaps more generally, the pleasantness of food. Potentially as a result of HF/HC food items being more pleasant and thus having a higher incentive value, it seems as though seeing these foods results in a response readiness, or an overall alerting effect, in the human brain.

The main goal of this research is to investigate how people with different cultural background differ in their interaction style and visual behavior on search engine results pages (SERP), more specifically between groups from the Middle Eastern region vs. Western Europe. We conducted a controlled eye-tracking experiment to explore and evaluate the visual behavior of Arabs and Spaniardusers when scanning through the first page of the search results in Google. Big differences can be observed in the 4 aspects studied: U.A.E. participants stayed on the SERPs for longer, they read more results and they read each snippet in a more complete way than Spaniards. In Spain, people tended to scan the SERP, reading less text on each snippet, and choose a result among the first top rankedones without hardly seeing those in bottom positions.

Contexto: La idea principal es la creación de una empresa para la fabricación y comercialización de productos cosméticos de alta gama. A pesar del contexto de crisis económica en el que estamos envueltos estos últimos años y del que no parece que acabamos de salir, el sector de la cosmética está resistiendo la situación de forma envidiable. De la crisis, como dicen los economistas, “se saldrá y se volverá, todo es cíclico” y viendo la fortaleza que éste sector está mostrando unido a la necesidad de que nuestra economía abandone sectores muy deteriorados y sin una previsión positiva de futuro, la cosmética se postula con un futuro prometedor dentro del contexto económico español y europeo. “Vinci Cosmetics” es el nombre inicialmente pensado para que la nueva compañía inicie su andadura. Nombre con tintes latinos de la lejana época del imperio romano como homenaje a la rica herencia histórica de la ciudad del autor del proyecto - Tarragona. La cultura por cuidarse y sentirse bien, muy arraigada en la mentalidad latina y mediterránea, es un factor cultural clave para el desarrollo y futura evolución de esta industria. El slogan de la empresa, “Dieta Mediterránea para tu piel”, clarifica en buena medida la idea a desarrollar y los objetivos pretendidos por la estrategia empresarial. Objetivos: El objetivo esencial del TFC es elaborar un estudio detallado para la creación de una empresa de fabricación y comercialización de productos cosméticos de alta gama que abarque el management y la gestión por procesos de la empresa, la función de marketing, el tipo de operaciones y procesos a realizar, la gestión del factor humano y el presupuesto necesario para cubrir este ambicioso proyecto. En detalle, un completo plan de empresa que marque las directrices de la organización industrial que se pretende crear compuesto a su vez por cinco planes: plan de gerencia, plan de marketing, plan de operaciones, plan de recursos humanos y plan económico – financiero. Procedimientos: El proyecto tiene un alto componente de estudio de mercados y de marketing pero pretende también abarcar el management, los procesos de operación, el factor humano y el aspecto económico y financiero de las inversiones y presupuesto necesario. El estudio inicial centrará su esfuerzo en un análisis del mercado de la península ibérica, y, en función del avance y del progreso esperado por la empresa, la compañía podría extender su campo de acción a Europa aunque no antes de un medio plazo. “Vinci Cosmetics” ha adoptado referenciales de sistemas de gestión integrados en toda la organización. Así tenemos principalmente, por un lado, la norma internacional ISO 9001:2008 y, por otro, el Modelo EFQM de Excelencia en la gestión; ambos plasmados a partir de un enfoque basado en procesos que nos garantiza el control continuo y la gestión excelente. Conclusiones: Tras evaluar la situación actual del mercado de la cosmética, las previsiones futuras de éste y las necesidades que una organización industrial necesita, se puede crear - con plenas garantías de éxito como organización empresarial y desde el punto de vista económico - una empresa de cosméticos de alta gama para cubrir las necesidades de una parte de mercado que lo requiere.

OBJECTIVES: To evaluate whether adult specialists comply with the basic principles for a successful transition of adolescents with chronic disorders, and to determine whether the characteristics of the adult specialists have an influence on applying these principles. METHODS: Out of 299 adult specialists in four French-speaking Swiss cantons, 209 (70%) answered a paper-and-pencil mailed questionnaire between May and July 2007. Only those having received the transfer of at least one adolescent in the previous 2 years (N=102) were included in the analysis. We analyzed four dependent variables: discussing common concerns of adolescent patients, seeing the patient alone, having a transition protocol, and having a previous contact with the pediatric specialist. A logistic regression was performed for each dependent variable controlling for the physicians' characteristics (number of transfers, age, gender, workplace, and perceived experience). RESULTS: Fifty-four percent of the physicians did not spend time alone with their patients, and sensitive issues such as sexuality or substance use were not widely discussed with their young patients. Most respondents (59%) did not have an established protocol, and 54% did not have any contact with the pediatric specialist. In the multivariate analyses, the adult specialists' characteristics had little impact. CONCLUSIONS: For many adolescents with chronic disorders the transition from pediatric to adult healthcare seems to be limited to a simple transfer, often lacking adequate communication between physicians. Applying simple but basic principles such as a good coordination between providers would probably improve the quality of healthcare of adolescents with chronic illness.

Partant de deux études de cas, le projet de Frente Ribeirinha à Porto (Portugal) et celui d'Euroméditerranée à Marseille, ce projet de thèse a pour objectif l'étude des modalités de valorisation du tissu bâti (patrimonialisation) par les acteurs institutionnels dans les projets de régénération urbaine. Suivant l'hypothèse de l'entrée dans un nouveau régime de patrimonialité, l'analyse doit expliciter les stratégies à l'oeuvre ainsi que la manière dont les autorités publiques influent sur les représentations de l'espace construit. Abordant la question des échelles d'intervention des projets de régénération urbaine à partir des deux études de cas, mais également de littératures sur des projets anglo-saxons, la thèse cherche à voir, au prisme de la construction patrimoniale, comment ces projets sont directement connectés à l'économie internationale et au phénomène de globalisation et s'ils prennent en compte l'échelle du quotidien et de la domesticité. Il s'agit de montrer les limites d'une valorisation du tissu bâti dans un objectif de retombées économiques (ville consommable) au détriment des valeurs d'usage et de signifiants du quotidien. D'où l'hypothèse de l'importance d'une prise en compte des représentations de valeurs aux différentes échelles (dimensions socio-culturelles du projet de régénération) pour un équilibre qualitatif dans la fabrication du territoire et des projets sur le long terme. La volonté est sensiblement la compréhension des nouvelles constructions patrimoniales ainsi que des pratiques de conception et de mise en oeuvre du projet urbain. - Based on two case studies, the Frente Ribeirinha project in Porto (Portugal) and Euroméditerranée in Marseille, this research project aims at studying the modes of enhancement of the built fabric by institutional actors in urban regeneration projects. Posing the idea of a new heritage regime, this analysis attempts to explain the different strategies at work and how public authorities influence the built space's representations. Looking at the different scales of intervention of regeneration projects in our two case studies, as well as Anglo-Saxon literature on projects, it seeks at seeing, through heritage processes, how these projects are directly connected to the international economy and the phenomenon of globalization. Also, it aims at investigating whether policies take into account the scale of everyday life and domesticity. It attempts to show the limit of a built fabric's valuation with economic benefits objectives (consumable city) rather than taking into account values and meanings of everyday life. Hence, the thesis suggests taking into account representations and values at different scales (socio-cultural dimensions of the regeneration project) for a qualitative balance in urban planning and urban projects' manufacturing. The aim is to broaden the understanding on heritage construction, on urban design practices and on implementation of urban projects.

BACKGROUND: The aim of this study was to explore the predictive value of longitudinal self-reported adherence data on viral rebound. METHODS: Individuals in the Swiss HIV Cohort Study on combined antiretroviral therapy (cART) with RNA <50 copies/ml over the previous 3 months and who were interviewed about adherence at least once prior to 1 March 2007 were eligible. Adherence was defined in terms of missed doses of cART (0, 1, 2 or >2) in the previous 28 days. Viral rebound was defined as RNA >500 copies/ml. Cox regression models with time-independent and -dependent covariates were used to evaluate time to viral rebound. RESULTS: A total of 2,664 individuals and 15,530 visits were included. Across all visits, missing doses were reported as follows: 1 dose 14.7%, 2 doses 5.1%, >2 doses 3.8% taking <95% of doses 4.5% and missing > or =2 consecutive doses 3.2%. In total, 308 (11.6%) patients experienced viral rebound. After controlling for confounding variables, self-reported non-adherence remained significantly associated with the rate of occurrence of viral rebound (compared with zero missed doses: 1 dose, hazard ratio [HR] 1.03, 95% confidence interval [CI] 0.72-1.48; 2 doses, HR 2.17, 95% CI 1.46-3.25; >2 doses, HR 3.66, 95% CI 2.50-5.34). Several variables significantly associated with an increased risk of viral rebound irrespective of adherence were identified: being on a protease inhibitor or triple nucleoside regimen (compared with a non-nucleoside reverse transcriptase inhibitor), >5 previous cART regimens, seeing a less-experienced physician, taking co-medication, and a shorter time virally suppressed. CONCLUSIONS: A simple self-report adherence questionnaire repeatedly administered provides a sensitive measure of non-adherence that predicts viral rebound.

Seeing and analyzing crowd control : considerations on the study of festive gatherings through the use of audiovisual material. The goal of our research project was to analyze the mechanisms of crowd control on the occasion of the 2008 European Football Championship held in Geneva. In this article, we describe the necessary ambiguity of these occasions for public authorities. On the one hand, they must guarantee that the occasion is sufficiently secure to avoid infractions or incivilities by fans ; on the other hand, they must create the conditions for a festive event of which exuberance is a central part. Police forces aim not to eliminate excesses but to contain them, since some degree of excess is indispensable to ensure the accomplishment of the event. How does the police deal with this complicated situation ? Where is the limit between preventive and repressive measures ? How do they implement management of the public order in the setting of a sports event ? We aim to render visible the practical conditions of the event by making use of video sequences recorded during a match in Geneva. The empirical materials collected will be used to describe three different situations that highlight how quickly fan action can radically switch natures and how complex it is for the police to face a jubilant crowd. In such a context, we show that assuring the smooth progress of the event requires a redefinition of the role of the police, whose interventions must tread a fine line between permissiveness and prohibition.

In this paper we consider a general action principle for mechanics written by means of the elements of a Lie algebra. We study the physical reasons why we have to choose precisely a Lie algebra to write the action principle. By means of such an action principle we work out the equations of motion and a technique to evaluate perturbations in a general mechanics that is equivalent to a general interaction picture. Classical or quantum mechanics come out as particular cases when we make realizations of the Lie algebra by derivations into the algebra of products of functions or operators, respectively. Later on we develop in particular the applications of the action principle to classical and quantum mechanics, seeing that in this last case it agrees with Schwinger's action principle. The main contribution of this paper is to introduce a perturbation theory and an interaction picture of classical mechanics on the same footing as in quantum mechanics.

Action representations can interact with object recognition processes. For example, so-called mirror neurons respond both when performing an action and when seeing or hearing such actions. Investigations of auditory object processing have largely focused on categorical discrimination, which begins within the initial 100 ms post-stimulus onset and subsequently engages distinct cortical networks. Whether action representations themselves contribute to auditory object recognition and the precise kinds of actions recruiting the auditory-visual mirror neuron system remain poorly understood. We applied electrical neuroimaging analyses to auditory evoked potentials (AEPs) in response to sounds of man-made objects that were further subdivided between sounds conveying a socio-functional context and typically cuing a responsive action by the listener (e.g. a ringing telephone) and those that are not linked to such a context and do not typically elicit responsive actions (e.g. notes on a piano). This distinction was validated psychophysically by a separate cohort of listeners. Beginning approximately 300 ms, responses to such context-related sounds significantly differed from context-free sounds both in the strength and topography of the electric field. This latency is >200 ms subsequent to general categorical discrimination. Additionally, such topographic differences indicate that sounds of different action sub-types engage distinct configurations of intracranial generators. Statistical analysis of source estimations identified differential activity within premotor and inferior (pre)frontal regions (Brodmann's areas (BA) 6, BA8, and BA45/46/47) in response to sounds of actions typically cuing a responsive action. We discuss our results in terms of a spatio-temporal model of auditory object processing and the interplay between semantic and action representations.

Iowa’s traffic safety culture is influenced by laws and policies, enforcement methods, driver education, roadway engineering, and drivers’ behaviors. The Center for Social and Behavioral Research at the University of Northern Iowa was contracted by the Iowa Department of Transportation to conduct a general population survey of adult Iowans. Telephone interviews were conducted with 1,088 adult Iowans from October to December 2011. A dual-frame (cell phone and landline) sampling design was used. The interview covered a wide range of traffic safety topics (e.g., traffic safety policies, enforcement techniques, and distracted driving). Most Iowans said driving in Iowa is about as safe now as it was 5 years ago; however, one-fourth said driving in Iowa is less safe now. There are a number of driving-related behaviors many adult Iowans consider serious threats to traffic safety and never acceptable to do while driving. Yet, many Iowans report often seeing other drivers engaging in these behaviors and admit engaging in some themselves. For example, nearly 1 in 5 adult Iowa drivers said they have sent or read a text message or email while driving in the past 30 days despite this being prohibited since July of 2011. A slight majority said they support using cameras on highways, interstates, and city streets to automatically ticket drivers for speeding, with even stronger support for red light cameras. A comprehensive approach to traffic safety in Iowa is required to encourage protective factors that enhance traffic safety and reduce the impact of detrimental factors.
