Made available in DSpace on 2016-04-04T18:36:28Z (GMT). No. of bitstreams: 1 antoniomarcio.pdf: 1148802 bytes, checksum: 9e97b45ffebf7610a371c540dc99fa5f (MD5) Previous issue date: 2007-03-19 / In the last 11 years, the Brazilian institutions of higher education passed through several transformations due to the higher education opening politics made by the Federal Government. This opening made a great number of students come back to the classrooms, which forced the IES, in many cases, to review its positions, information and communication processes, and to search new indicative of management and evaluation. The instauration by the Brazilian Government of the SINAES - National System of Evaluation of Higher Education in April 14 of 2004 imposed ten evaluatives dimensions that started to be followed by the higher education institutions. In this direction, this work is a case study developed in the Uni?o Social Camiliana and aim to evaluate, through the parameters proposed by the SINAES, how this organization is structured considering the communication and information processes. Improvements are also considered based in the concepts of Information Management and Competitive Intelligence. This evaluation was made through two instruments: applied questionnaires and reports collected in the institution. As a result of this process, we perceive that the Information Management and Competitive Intelligence can assist the IES to deal with varied information and communication contents, contributing for the improvement of the management processes and leading to match the SINAES requirements. This work proposes improvements in the communication and information processes in the Uni?o Social Camiliana, using of the concepts of Information Management and Competitive Intelligence. / Nos ?ltimos 11 anos, as Institui??es de Ensino Superior (IES) brasileiras sofreram uma s?rie de transforma??es devido ?s pol?ticas de abertura do Ensino Superior criadas pelo Governo Federal. Esta abertura fez com que uma grande massa de alunos voltasse ?s salas de aula, o que obrigou as IES, em muitos casos, a rever seus posicionamentos, processos comunicacionais e informacionais e buscar novos indicativos de gest?o e de avalia??o. A instaura??o do SINAES Sistema Nacional de Avalia??o do Ensino Superior, em 14 de abril de 2004 pelo Estado, institucionalizou dez dimens?es avaliativas que come?aram a ser seguidas pelas institui??es de ensino. Nesse sentido, este trabalho ? um estudo de caso desenvolvido na Uni?o Social Camiliana e procura avaliar, por meio dos par?metros propostos pelo SINAES, como a organiza??o est? estruturada no que se refere aos processos de comunica??o e informa??o e, com base nos conceitos de Gest?o da Informa??o e Intelig?ncia Competitiva, propor melhorias. Esta avalia??o foi realizada por meio de dois instrumentos: question?rios aplicados e relat?rios coletados na Institui??o. A partir dela, percebemos que a Gest?o da Informa??o e a Intelig?ncia Competitiva podem auxiliar as IES a lidar com conte?dos informacionais e comunicacionais diversos, contribuindo para melhoria dos processos de gest?o e melhor articula??o das propostas do SINAES. Este trabalho prop?e melhorias nos processos de comunica??o e informa??o da Uni?o Social Camiliana, utilizando-se dos conceitos de Gest?o da Informa??o e Intelig?ncia Competitiva

Le défi français à la prééminence anglaise au Brésil, 1822-1850 / The French challenge to the English preeminence in Brazil, 1822-1850

Grosse, Philippe 14 December 2015 (has links)
La France possède une industrie qui en couvre les principales branches, dimensionnée pour faire face aux besoins de la consommation, mais partie avec retard dans la révolution industrielle, elle n’est pas apte à soutenir la concurrence de nations rivales plus avancées; le gouvernement est contraint d’appliquer des mesures protectionnistes pour sauvegarder l’emploi; de nombreuses institutions ont pour but de favoriser le développement du commerce et de l’industrie; mais les Français ont un esprit d’entreprise peu développé; la prudente circonspection des négociants français s’oppose au caractère hardi et aventureux des Anglo-saxons. La Grande-Bretagne s’est dotée, surtout dans le textile, d’un outil de production industrielle innovant et performant, dimensionné pour dépasser largement les besoins du marché intérieur; ses négociants et ses fabricants possèdent un esprit qui les tourne vers le commerce extérieur dans leur recherche de profit; enfin le pays possède des institutions financières solides et une flotte de commerce à laquelle le Navigation Act pris sous Cromwell a permis de donner un grand développement; mais une détresse profonde qui sévit dans les classes laborieuses vient sérieusement ternir ce tableau flatteur. Entre 1822 et 1850 la France voit la production de son industrie manufacturière plus que doubler, son commerce extérieur tripler; elle double la part de marché qu’elle possède dans les exportations de produits naturels et manufacturés au Brésil; cela constitue pour la France une réussite, mais n’aurait elle pas pu mieux faire? La thèse tente d’apporter des éclairages sur les responsabilités relatives de la politique suivie par le gouvernement et du comportement des acteurs privés. / The French industry covers the main branches of which it is composed, and is designed to cope with the consumption of the country; but having started tardily it cannot withstand the competition of more advanced rival nations; the government has to promote protectionist measures to safeguard employment; numerous institutions exist to boost the development of trade and industry; but French people lack the spirit of enterprise; the prudent circumspection of French merchants is opposed to the bold and adventurous character of Anglo-Saxons. Great Britain has developed, mainly in their textile industry, an innovating and performing tool for industrial production, designed to exceed considerably the needs of domestic market; the merchants and manufacturers have a spirit oriented toward international trade to make a profit; and the country has solid financial institutions and a merchant shipping to which the Navigation Act promulgated by Cromwell gave a big advantage; but a big distress which exists in the working classes tarnishes this flattering landscape. Between 1822 and 1850 the production of French industry more than doubled, the foreign trade tripled; and its market share for exports of natural and manufactured products to Brazil doubled; this was a success for France, but could she have done better? The thesis tries to throw some light on the comparative responsibilities of the governmental policies and the behaviour of the private sector.

La "langue de bois" au Royaume-Uni au 21ème siècle : une étude sémiolinguistique du parler politique contemporain / "Doublespeak" in the United Kingdom in the 21st century : a semiolinguistic study of contemporary political speech

Nimtz, Julie 09 November 2018 (has links)
Cette thèse se donne pour objet l’étude du fonctionnement de ce que l’on appelle « langue de bois » dans le discours politique contemporain au Royaume-Uni. Cet hyperonyme désigne un ensemble de stratégies déployées en langue, selon des modes divers, à des fins manipulatoires. Ce travail distingue ainsi, au sein de ce discours « codé », des procédés linguistiques qui relèvent de ce que nous appelons parler politique contemporain qui, insidieusement, diffuse une idéologie dominante. Bien qu’aucun procédé, linguistique ou rhétorique, ne soit intrinsèquement manipulatoire, ce parler remplit différentes fonctions selon le contexte (linguistique, générique, situationnel). L’exploration d’un corpus de general election manifestos comparé à un corpus d’éditoriaux britanniques vise à mettre au jour le fonctionnement sémiolinguistique de ce parler, manifestation d’une activité de construction de valeurs idéologiques et/ou de manipulation langagière. Notre étude linguistique s’appuie sur la Théorie des Opérations Prédicatives et Énonciatives d’A. Culioli, complétée par le recours à d’autres théories (Analyse du/des Discours et sémiotique). Les phénomènes linguistiques sont contextualisés au moyen d’autres disciplines (sociologie et sciences politiques). Partant du principe que le sens idéologique et les valeurs destinées à être reconnues, reconstruites et interprétées, sont construits dans et par l’énonciation, nous montrons, au moyen de l’analyse de marqueurs (WILL, SHALL, WOULD, les pronoms personnels YOU, WE, I) et de notions (/change/ et /be green/), que la co-énonciation est une clé essentielle pour la compréhension des stratégies manipulatoires mises en œuvre au sein de ce parler. Les opérations fondamentales de « représentation », « référenciation », « régulation » (Culioli) et les stratégies de naturalisation et/ou d’oubli (Barthes/Pécheux) déployées au sein des textes se présentent sous différentes formes, parmi lesquelles on peut citer l’ajustement anticipatif paratextuel, et le brouillage des frontières entre différents niveaux de spécification du paramètre S de la situation d’énonciation ou entre les différentes valeurs construites par les auxiliaires de modalité/les notions. / The purpose of this thesis is to study the workings of what is usually called “langue de bois” in French (Newspeak or Doublespeak) in the field of politics in the United Kingdom. The collocation refers to a set of strategies implemented within political discourse, according to various modes, for manipulative purposes. We propose to differentiate between Newspeak-like strategies and linguistic processes belonging to the realm of contemporary political speech (CPS) which circulates a dominant ideology insidiously. Although no process, be it linguistic or rhetorical, is inherently manipulative, CPS fulfils various functions depending on the context (linguistic, generic, situational). The study of a corpus of general election manifestos compared to a corpus of editorials aims at uncovering the semiolinguistic workings of CPS, the expression of how ideological values and/or linguistic manipulation are constructed. Our linguistic study is conducted through the lens of the Theory of Predicative and Enunciative Operations (A. Culioli), supported by comparisons with other linguistic theories (Discourse Analysis and semiotics). The linguistic phenomena are contextualized by means of other disciplines (sociology and political sciences). Considering the fact that ideological meaning and values designed to be recognized, reconstructed and interpreted, are constructed through and by uttering, we show, through the analysis of markers (WILL, SHALL, WOULD, and the pronouns YOU, WE, I) and of notions (/change/ and /be green/), that co-enunciation is essential to the understanding of manipulative strategies that are implemented within CPS. The fundamental operations of “representation”, “referencing”, “regulation” (Culioli) and naturalisation/forgetting processes (Barthes/Pécheux) that are implemented within the texts arise in various forms. Among these forms, markers of anticipatory paratextual adjustment, and the scrambling of boundaries between the levels of specification of the subjective parameter of the situation of uttering or between the various values constructed by modal auxiliaries/notions can be mentioned.

Transporte de portadores minoritários que justificam o regime de ressonância eletrônica em sistemas de carbynes

Oliveira, Antônio Wanderley de 24 February 2016 (has links)
Uma das metas para a expansão do conhecimento em eletrônica molecular pode ser encontrada no projeto relacionado com a criação de circuitos em nanoescala com base em características de corrente-tensão não lineares, composto por moléculas ligadas a eletrodos metálicos sob a ação de um campo elétrico externo. O desenvolvimento de dispositivos eletrônicos moleculares que utilizam sistemas exibindo recursos semelhantes como materiais semicondutores intrínsecos é uma das metas a serem atingidas por uma extensa pesquisa em nanotecnologia. Assim, este trabalho tem como objetivo a expansão do conhecimento não só do transporte eletrônico, mas também as características físicas que justificam o regime de ressonância para o transporte eletrônico, como a condutância e Espectroscopia de Voltagem de Transição. Foi investigado teoricamente o transporte de carga eletrônica em um sistema molecular composto por estruturas de carbyne levando em conta as variações nos tipos de ligações −≡− (ligações simples e triplas para cada carbono). Os cálculos e aproximações ab initio são realizados para investigar a distribuição de estados de elétrons através da molécula na presença de um campo elétrico externo. Este novo dispositivo nanoeletrônico suscitará vantagem para o projeto de grandes circuitos orgânicos/metálicos híbridos 1D com um aumento do fluxo eletrônico que é importante para as necessidades da nanotecnologia. / One of the goals for the expansion of knowledge in molecular electronics may be found in the Project related to the creation of nanoscale circuits based on nonlinear current–voltage characteristics composed by molecules connected to metallic electrodes under the action of an external electric field. The development of molecular electronic devices using systems exhibiting similar feature as intrinsic semiconductor materials is one of the goals to be achieved by an extensive research in nanotechnology. Thus, this work aims at expanding of knowledge not only of the electronic transport, but also the physical features that justify the resonant regime for electronic transport, such as conductance and Transition Voltage Spectroscopy. We theoretically investigate the electronic charge transport in a molecular system composed by carbyne structures taking into account the variations in the bonds −≡− type (simple and triple bonds for each carbon). Ab initio calculations approximations are performed to investigate the distribution of electron states over the molecule in the presence of an external electric field. This new nanoelectronic device raise up advantage for the design of large 1D hybrid organic/metallic circuits with an increased electronic flow that is importante for the needs of nanotechnology.

It also brings a brief history of the creation of the European Union, described with relevant information to the empirical study. The data from the Penn World Table 8.0 are used for the analysis of the technical change in countries that joined the European Union until 1995, in the period 1950-2011, adopting the Foley and Michl (1999) representation system, which uses the growth-distribution schedule. It also analyzes the results of the variables: growth rate of capital stock, real average wage and gross profit rate. The study finds a Marx-biased technical change in the member states, common in capitalist economies. Moreover, the results of the evolution of labor productivity and capital intensity show an approximation process in relation to the United States in the period 1970-2011, observing the effects of economic integration. The results of the difference between the growth rates of the capital stock of the EU-15 and the US economy show a downward trend in the same period in almost all regions. / O trabalho apresenta a teoria do processo de integra??o na vis?o do economista h?ngaro B?la Balassa, al?m de outros autores, comentando sobre as etapas da evolu??o e a diminui??o das barreiras ? medida que a integra??o evolui.

The research is built on the theory of labeling, demonstrating how the deviation is built through the implementation of concepts of normality in society, defining the relationship between people of the same sex as an abnormality. The speeches are analyzed through the Critical Discourse Analysis, focusing on forms of abuse of power to analyzing how discourses are inserted in society and result in social inequalities. The goal is to analyze, in the polarization of groups, how the progressive and conservative discourses articulate recognition of marriage between same sex, or defines it as a deviation from the traditional notion of family. Through the discourse analysis this study seeks to deepen, critically, the procedures of the action of developing the labeling, through the production of oral and written discourses, by which interpretations are built and shared by the institutions and social forces in the construction of the relationship between people of the same sex as a deviation. / Nossa proposta ? analisar, nos discursos de reconhecimento e equipara??o, na decis?o do STF como se articulam os argumentos de conservadores e progressistas em torno do conceito de fam?lia previsto na constitui??o sobre ?s rela??es homoer?ticas no Brasil.

Les effets des dimensions culturelles sur l'évaluation des produits domestiques : cas des produits d'ameublement domestiques par les consommateurs européens / Cultural dimensions effects on products evaluation : furnishing domestic product evaluated by european consumer

Boyom, Charlène 21 November 2012 (has links)
Cette thèse examine les effets de la culture sur l’évaluation et l’intention d’achat des produits domestiques versus étrangers dans deux pays (France et Royaume-Uni).Les individus interrogés ont reçu des informations sur deux produits d’ameublement(canapés) fabriqués soit en France soit au Royaume-Uni. Les produits étaient décrits comme étant supérieurs ou inférieurs à la concurrence étrangère. Il s’avère que les français et les anglais évaluent favorablement les produits domestiques (versus importés) lorsqu’ils sont supérieurs à la concurrence étrangère. En outre, le pays d’origine du produit va plus influencer l’intention d’achat des produits domestiques chez les anglais que chez les français. Les dimensions individualisme horizontal, distance hiérarchique et masculinité expliquent les effets de la culture sur l’évaluation et l’intention. Cela donne lieu à de nombreuses implications sur les stratégies de marketing international dont les solutions sont proposées dans cette recherche. / This thesis examines the effects of culture on the evaluation and purchase intention of domestic versus foreign products in two countries (France and United-Kingdom). Subjects received information about two furnishings products (sofas) manufactured in either France or the United-Kingdom. The products were described as being superior or inferior to foreign competition. It turns out that the French and English respondents evaluated favorably domestic products (versus imported ones) only when they are superior to competition. In addition, the country of origin of the product will most influence the intention to buy domestic products in United- Kingdom than in France. The horizontal dimension of individualism, the power distance and the masculinity explain the effects of culture on product evaluation and purchase intention. This gives rise to many implications on international marketing strategies whose solutions are proposed in this research.

Diffusion et évolution des mouvements sociaux dans les longues années soixante au Royaume-Uni : 1956-1979 / Diffusion and evolution of social movements during the Long Sixties in the United Kingdom : 1956-1979

Mansour, Claire 14 September 2018 (has links)
Au cours de la période des longues années soixante, le Royaume-Uni fut traversé par un cycle de contestation lors duquel différents groupes de militants firent valoir un large éventail de revendications. Un certain nombre de similarités peut être observé dans leurs idéologies, leurs tactiques et leurs symboles, comme par exemple leur volonté de lutter pour leur « libération » de « l’oppression » impérialiste, paternaliste, raciste, sexiste, homophobe ou même de délivrer les animaux de la domination humaine. Ces similitudes suscitent logiquement de nombreuses questions, notamment les suivantes : comment expliquer ces parallèles ? Quels sont les liens qui ont rendu possible la diffusion de ces éléments ? Dans quelle mesure la diffusion a-t-elle contribué à l’évolution de la contestation dans les longues années soixante au Royaume-Uni ? Afin d’y répondre, cette thèse s’efforcera d’analyser séparément les différents mouvements sociaux de la période, en accordant une importance particulière à leurs interactions et à leurs rôles au sein du cycle. En fournissant un modèle aux groupes de militants qui l’adaptent ensuite à leur propre cause, les processus de diffusion viennent nourrir et amplifier la dynamique protestataire. Il ne s’agit donc pas d’un simple phénomène de mimétisme, mais d’un procédé créatif témoignant d’activités complexes de construction du sens. Le choix de la source d’inspiration est également très significatif, d’autant plus que celle-ci peut se situer dans un autre pays ou une autre époque. Ainsi, il conviendra de démontrer que la diffusion peut opérer de manière diachronique au sein d’un même territoire, comme de manière synchronique lorsque les militants jettent leur dévolu sur un mouvement aux revendications différentes ou ayant lieu à l’étranger. / During the Long Sixties, the United Kingdom witnessed the rise of a protest cycle allowing various groups of activists to press for a wide array of claims. A number of similarities can be observed in their ideologies, tactics and symbols, such as their willingness to fight for their “liberation” from “oppression”, be it imperialist, paternalistic, racist, sexist, homophobic or even to free animals from human domination. These analogies raise a number of questions, notably: how can these parallels be explained? What are the links that enabled the diffusion of these elements? To what extent did diffusion processes contribute to the evolution of protest during the Long Sixties in the United Kingdom? To answer these questions, this thesis will analyse the social movements of the period separately, whilst paying particular attention to their interactions with one another and their role within the protest cycle. By providing other groups of activists with a model that they can adapt to their own cause, diffusion processes can swell and escalate the dynamics of contention. Hence, they differ from pure mimicry; they show how meaning is carefully constructed through creative adaptations. The choice of a particular source of inspiration is also very significant, especially when it can be traced back to another era or country. Therefore, it will be demonstrated that diffusion can occur both diachronically within national boundaries or synchronically between movements making different claims or taking place in a different country.

Dynamic characterisation of vibration isolators

Dickens, John D., Aerospace & Mechanical Engineering, Australian Defence Force Academy, UNSW January 1998 (has links)
A vibration isolator is designed to reduce the vibration and structure borne noise transmitted from a vibratory source, such as machinery and equipment, to the supporting structure. The vibration and structure borne noise transmitted depends upon the dynamic properties of the foundation, the source mounting point and the vibration isolator. Therefore knowledge of the frequency dependent dynamic properties of vibration isolators is a necessary part of the acoustic prediction and control/reduction process. Vibration isolators may be characterised by measuring their four-pole parameters. A measurement procedure is proposed that employs the floating mass method, measures the direct forces and corrects for the errors introduced by the direct force measurement. Compared to the basic method, it extends the frequency limits of measurement in both directions. The development of a novel vibration isolator test facility that implements the proposed measurement procedure is described, and its satisfactory operation is experimentally demonstrated. The vibration isolator test facility is capable of characterizing vibration isolators commonly used in industrial and maritime applications, under service conditions. A method is proposed for measuring the four-pole parameters of a uni-directional asymmetrical vibration isolator under static load. The method is called the two masses method, and is suitable for determining the four???pole parameters of active vibration isolators with feedback control. The method is also applicable to uni-directional symmetrical and bi-directional symmetrical and bi-directional asymmetrical vibration isolators. It may be regarded as a universal method for characterising vibration isolators. Experimental data is presented and the method is validated. Modelling of vibration isolators is complicated by the highly non-linear nature of their rubber elements. The notion of an effective rubber cylinder is proposed to account for the barrelling of rubber elements under static load. Consequently, a general static compression model is proposed that applies to vibration isolators having unfilled and filled rubber elements of regular prismatic shapes. The model predicts the dependence of the four-pole parameters on the compression ratio of the rubber element. The predictions derived from the effective rubber cylinder and general static compression model agree excellently with experimental work of this study and other researchers.
