La construcció de l'església de Sant Feliu de Girona al segle XIV. Els llibres d'obra

Aquesta tesi doctoral com diu el seu títol es centra en analitzar la construcció de l'església de Sant Feliu de Girona al segle XIV a través de l'anàlisi dels llibres d'obra conservats a l'Arxiu Diòcesa de Girona. Aquesta tesi doctoral esta dividida en quatre parts. En la primera part s'analitza la historiografia de l'església de Sant Feliu de Girona des del segle XVII fins a l'actualitat. Dins d'aquest apartat s'analitzen les notícies que aporten els diferents autors i es situa el context historiogràfic de cadascun dels segles. S'ha realitzat un estudi molt exhaustiu en les darreres publicacions del segle XX i inicis del segle XXI. Un cop analitzades aquestes fonts - secundàries -, dins d'aquesta primera part del treball s'ha passat a analitzar els llibres d'obra del segle XIV. S'analitzaràn els aspectes formals i els diferents escrivans encarregats de realitzar aquests llibres d'obra. Aquesta serà la documentació bàsica per realitzar aquesta tesi doctoral. En la segona part del treball es procedirà a analitzar la gestió i el finançament de l'Obra. Es tracta d'una anàlisi, bàsicament dels ingressos, per veure quines són les estratègies que es duen a terme per aconseguir el màxim de recursos per la construcció i per les necessitats "litúrgiques" de l'església de Sant Feliu de Girona. En aquest apartat s'ha analitzat l'Obra com a entitat amb les persones que formen part d'ella i el paper que correspon a cadascuna d'elles (l'obrer, l'escrivà, el mestre d'obres, el questor). També s'han analitzat els promotors i aquells ingressos que, pel seu volum, subministren el nombre més gran de diners a l'Obra ("annates", bacins, etc.). La tercera part ha consistit en l'elaboració de la cronologia constructiva de l'església de Sant Feliu de Girona partint de la informació obtinguda en els llibres d'obra corresponent a les despeses. S'han analitzat totes aquelles obres, tant pel que fa a la construcció de l'edifici com pel que fa a reparacions i manteniment, que tenen lloc entre l'any 1349 (data del primer llibre d'obra de despeses) i l'any 1391. En aquesta part no s'ha entrat a analitzar de forma exhaustiva les figures que fan possible la construcció de l'església al segle XIV ja que això pertany al contingut de la darrera part del nostre treball. La darrera part del treball correspon a l'execució de les obres. En aquesta part trobem quatre grans capítols: els mestres d'obra, la mà d'obra, els materials i els mitjans auxiliars. En cadascun d'aquests capítols s'ha incidit sobre el rol dels diferents treballadors durant la construcció del temple, els materials utilitzats i les seves característiques (pedra, fusta, aglomerants, etc.) i els mitjans auxiliars utilitzats per col.locar aquests materials en obra. S'han separat els mestres d'obres de la resta de treballadors ja que els primers juguen un rol diferenciat dels segons. S'ha intentat analitzar en ambdós casos els seus sous i les tasques de cadascun d'ells. Pel que fa als materials també s'ha procedit a analitzar d'on s'extreuen, com han arribat a peu d'obra i on s'emmagatzemen i manipulen o transformen abans d'ésser col.locats en obra. Dels mitjans auxiliars s'ha intentat analitzar les funcions per la qual es fan servir les eines (apareixen totes les de l'ofici de pedrer), els enginys (elevar pesos), les bastides (poder treballar en alçada) i el encofrats (garantir la resistència inicial dels elements constructius). Evidentment s'han establert unes conclusions de cadascuna de les parts i unes conclusions finals. La tesi també inclou els agraïments corresponents, el prefaci i la bibliografia.

Reposicionamento da marca Portugal

RESUMO: A Marca de um País também vende. A imagem de um País é nos dias de hoje um activo muito importante para a sua economia. Uma marca é uma promessa feita ao consumidor, é o ponto de referência de todas as impressões, positivas e negativas adquiridas ao longo do tempo. O Marketing é a ferramenta que deverá percepcionar, estudar e apresentar factores de diferenciação, mostrar e convencer os consumidores das qualidades de um produto ou serviço. A realidade impõe uma atenção especial ao tema e a Marca Portugal teve um boom de programas de desenvolvimento e de promoção a partir dos anos 90 do séc. XX. O responsável pela gestão da Marca Portugal é o Governo, através da AICEP, Agência para o Investimento e Comércio Externo de Portugal, que tem como missão aumentar a notoriedade de Portugal, dinamizando o investimento estruturante e a internacionalização das empresas, criando condições competitivas e estimulando a exportação no Mercado Global, diversificando a oferta dos produtos e os Países de Destino. A falta de estratégia e os planos mal sucedidos, são alguns dos erros apontados à gestão da Marca Portugal, mas é determinante assumir claramente que a assumpção da Marca e o seu Reposicionamento é um vector estratégico para o desenvolvimento do País. Portugal tem boas referências, na indústria, nos serviços, tem produto, que podem ajudar a promover a imagem global de Portugal e contribuir para o aumento das receitas, seja das exportações, do Turismo ou do Investimento Estrangeiro. Portugal precisa de um Plano de Marketing e de uma entidade gestora de Marca, que garanta uma gestão eficaz da Marca Portugal, integrada e articulada com todos os produtos e serviços estratégicos para a exportação ou para o consumo interno. Esta dissertação apresenta um Modelo de Reposicionamento da Marca Portugal que agrega todos os pontos positivos que Portugal possui, como, a sua capacidade de vendas, o seu potencial para se investir, o que há para ser visitado, e desenvolve um programa sério e transversal que promova Portugal no estrangeiro e que atraia investidores e visitantes. ABSTRACT: The Brand of a Nation also sells. The image of a country is, nowadays, an important asset for its economy. A brand is a promise made to the consumer; it is the reference point for all impressions, positive and negative acquired over time. Marketing is the tool that must perceive, study and present differentiation factors, must show and convince consumers about the qualities of a product or service. Reality demands a special attention to this topic and the Portugal Brand experienced a development and promotion program boom since the 20th Century 90’s. Currently, the figure in charge of the management of the Portugal Brand is the Government, through AICEP, whose mission is to increase the notoriety of Portugal, captivating structural investment and the internationalization of enterprises, mainly small and medium businesses, creating competitive conditions and stimulating exports to the Global Market, diversifying product offer and Destination Countries. Some errors have been pointed out in the management of the Portugal Brand, such as lack of strategy and unsuccessful plans, but it is imperative to irrevocably understand that Brand assumption and its Repositioning is a strategic vector for the development of the Country. Portugal has good references, either in industry, or services, has product, that help promoting Portugal’s global image and contributing to an increase in revenues, either in exports, Tourism or Direct Investment. Portugal needs a Marketing Plan and a Brand management entity, such as a Brand strategic executive council, to ensure an effective management of the Portugal Brand, integrated and articulated with all the products and services flagged as strategic assets for exportation or domestic use. This thesis presents a Repositioning Model of the Portugal Brand that aggregates all positive aspects that Portugal has, such as sale capacity, potential for investment, lots of places to visit, and develops a serious and transversal program to promote Portugal abroad and to attract investors and visitors alike.

O impacto das novas biotecnologias no pensamento político

A dissertação de mestrado “O Impacto das Novas Biotecnologias no Pensamento Político – A problemática das células estaminais embrionárias” partiu do pressuposto basilar de que a Humanidade se depara com uma ruptura de modelo de pensamento sem paralelo na História. O Homem detém hoje um conhecimento científico sem precedentes e vê-se perante o potencial das novas biotecnologias que, pela primeira, vez podem alterar a forma de olhar sobre si próprio, não apenas enquanto ser social mas sobretudo como entidade biológica. Todo o enquadramento da dissertação tem em consideração os diferentes momentos da História em que certos homens levados pela inevitabilidade do progresso intelectual e científico contribuíram decisivamente para alterar profundamente os modelos de pensamento. Modelos que, surgidos em determinado contextos históricos, foram considerados de ruptura e revolucionários. Em sentido contrário, numa espécie de reacção conservadora, foram surgindo forças de autoridade e de poder, rejeitando novos modelos e paradigmas que, de uma maneira ou de outra, pudessem pôr em causa o sistema de sociedade instituído. As grandes rupturas na História da Humanidade resultaram desse confronto de ideias, entre um modelo de pensamento vigente e um novo paradigma proposto. Ao longo da dissertação apresentada são analisados vários períodos de ruptura, com particular enfoque para o advento da genética no século XIX e posterior revolução biotecnológica nos Estados Unidos que, num futuro próximo, poderá vir a curar doenças congénitas e degenerativas, funcionando como uma espécie de “kit de reparação do corpo humano, e, num horizonte mais alargado, poderá potenciar a possibilidade da criação de um “outro eu”, produto do Homem e não do livre arbítrio. Pela primeira vez, o Homem tem conhecimento e técnica para criar um mundo pós-humano, onde cada um é resultado da vontade individual dos seus progenitores, dando-se, assim, início a uma nova História. Mas, tudo isto levanta uma série de questões morais, éticas e políticas. Dilemas quanto aos processos de investigação e quanto às consequências que a sua aplicação poderá trazer para a própria Humanidade. Como trabalho de Ciência Política não cabe no propósito deste tecer cenários filosóficos quanto ao futuro do Homem face aos avanços da investigação genética, mas sim tentar analisar e procurar encontrar um padrão de comportamento na forma como os legisladores e governantes, mediante a sua base doutrinária, têm abordado uma matéria cujas implicações terão eventualmente impacto na concepção da própria Humanidade.

Museums as service providers

The present paper discusses the complex understanding of Museum as an entity that provides services. Indeed we are far from seeing museums fully acting as services since the rationale of the way they operate derives from the permanent concession of grants either from state budgets or from beneficent institutions. In order to do this, we use reflections presented in previous papers, where we considered these issues separately; we now believe they will gain some coherence when articulated with the reflection on museums seen in their possible, albeit inadequately assumed, condition as service providers.We shall consider some aspects of the introduction in museums of the new information and communication technologies (NICT) as part of this process. On the one hand, these technologies open doors, and some museums take good advantage of that; but on the other hand their being used in a limited way does not enable the realisation of the role they can play, with multiple benefits from the organisational point of view, fostering innovation and creating new service concepts that are more aware of the world we live in.

Gestão da qualidade: avaliação do processo de acreditação do Hospital Divina Providência

A temática desta pesquisa surgiu da análise do projeto de acreditação hospitalar do Hospital Divina Providência (HDP) junto à Organização Nacional de Acreditação - ONA do Governo Federal do Brasil – no município de Marituba da Região Metropolitana de Belém, objetivando mensurar o grau de entendimento dos colaboradores, usuários e gestores sobre o processo de Acreditação desenvolvido na Instituição. A metodologia utilizada para realização da pesquisa caracteriza-se como exploratória descritiva com abordagem quantitativa e quantitativa, de amostra probabilística por acessibilidade, aplicada aos três tipos de elementos acima mencionados, com o intuito de verificar, qual o nível de conhecimentos sobre o assunto abordado, e como eles veem a empresa inserida nesse tema. No decorrer do estudo, foi analisado quão grande tem se tornado a abordagem no Brasil e mundo, e como os hospitais têm adotado as certificações de qualidade como um fator de competitividade no mercado e de reconhecimento. Conclui-se que, a entidade não mantém um sistema de aprimoramento de gestão da qualidade com vistas a uma certificação de acreditação juntos aos colaboradores e gestores, de forma a auxiliá-los no desenvolvimento e amadurecimento do referido processo. Percebe-se também, que não há conformidade e nem integração de ideias a respeito do tema abordado entre gestores e colaboradores do HDP.

El levantamiento del velo en la doctrina y la jurisprudencia ecuatoriana

La persona jurídica es un centro de imputación diferenciado, en el cual se limita la responsabilidad patrimonial de quienes se asocian. sin embargo, a veces esta figura puede ser mal utilizada para alcanzar metas prohibidas por la ley o para perjudicar a terceros. La legislación ha previsto mecanismos para evitar esta utilización indebida de la persona jurídica, pero, excepcionalmente, se dan casos en que la solución legislativa no es suficiente, por lo que, partiendo de los principios generales del derecho de la buena fe, la lealtad y la equidad, la jurisprudencia ha desestimado la personalidad jurídica y ha llegado hasta quienes, amparándose en la figura societaria, han pretendido burlar la ley o abusar del derecho. Se ha desarrollado la teoría del regard of legal entity, que recibe muchos nombres en español (se ha preferido el de levantamiento del velo) que permite al juez, excepcionalmente, levantar el velo que separa al espectador de la realidad, a fin de imponer a los responsables del fraude o el abuso, la responsabilidad que les corresponda. en primer lugar se hace una breve exposición de la teoría, reseñando lo que han dicho los autores, para continuar examinando la situación ecuatoriana, las disposiciones legales aplicables y las sentencias en las cuales los jueces se han referido a esta teoría, y concluir señalando la naturaleza procesal de la figura, la inconveniencia de dictar una ley que la incorpore al ordenamiento jurídico y el riesgo de una utilización masiva e indiscriminada.

Turing Test: Mindless Game?

The Turing Test, originally configured for a human to distinguish between an unseen man and unseen woman through a text-based conversational measure of gender, is the ultimate test for thinking. So conceived Alan Turing when he replaced the woman with a machine. His assertion, that once a machine deceived a human judge into believing that they were the human, then that machine should be attributed with intelligence. But is the Turing Test nothing more than a mindless game? We present results from recent Loebner Prizes, a platform for the Turing Test, and find that machines in the contest appear conversationally worse rather than better, from 2004 to 2006, showing a downward trend in highest scores awarded to them by human judges. Thus the machines are not thinking in the same way as a human intelligent entity would.

A geometric algorithm for an artificial life form based on anachronistic methods

Modern methods of spawning new technological motifs are not appropriate when it is desired to realize artificial life as an actual real world entity unto itself (Pattee 1995; Brooks 2006; Chalmers 1995). Many fundamental aspects of such a machine are absent in common methods, which generally lack methodologies of construction. In this paper we mix classical and modern studies in order to attempt to realize an artificial life form from first principles. A model of an algorithm is introduced, its methodology of construction is presented, and the fundamental source from which it sprang is discussed.

The Brain as a Cultural Artefact

Where does biology end and culture begin? While the human body is now widely accepted as being both biological and cultural, the brain is still considered by archaeologists as being a biological entity that provides the capacity for culture and is subject to no further change after the evolution of Homo sapiens. This article reviews recent research that suggests that the brain has continued to evolve at an increasing rate in recent times under the influence Of culturally created environments and that both the anatomy and function of individual brains can be manipulated by cultural behaviour. It describes an experiment in which one of us successfully changed his own brain in response to his cultural activity.

A management architecture for active networks

In this paper we present an architecture for network and applications management, which is based on the Active Networks paradigm and shows the advantages of network programmability. The stimulus to develop this architecture arises from an actual need to manage a cluster of active nodes, where it is often required to redeploy network assets and modify nodes connectivity. In our architecture, a remote front-end of the managing entity allows the operator to design new network topologies, to check the status of the nodes and to configure them. Moreover, the proposed framework allows to explore an active network, to monitor the active applications, to query each node and to install programmable traps. In order to take advantage of the Active Networks technology, we introduce active SNMP-like MIBs and agents, which are dynamic and programmable. The programmable management agents make tracing distributed applications a feasible task. We propose a general framework that can inter-operate with any active execution environment. In this framework, both the manager and the monitor front-ends communicate with an active node (the Active Network Access Point) through the XML language. A gateway service performs the translation of the queries from XML to an active packet language and injects the code in the network. We demonstrate the implementation of an active network gateway for PLAN (Packet Language for Active Networks) in a forty active nodes testbed. Finally, we discuss an application of the active management architecture to detect the causes of network failures by tracing network events in time.

Distributed intelligent management of active networks

This paper focuses on improving computer network management by the adoption of artificial intelligence techniques. A logical inference system has being devised to enable automated isolation, diagnosis, and even repair of network problems, thus enhancing the reliability, performance, and security of networks. We propose a distributed multi-agent architecture for network management, where a logical reasoner acts as an external managing entity capable of directing, coordinating, and stimulating actions in an active management architecture. The active networks technology represents the lower level layer which makes possible the deployment of code which implement teleo-reactive agents, distributed across the whole network. We adopt the Situation Calculus to define a network model and the Reactive Golog language to implement the logical reasoner. An active network management architecture is used by the reasoner to inject and execute operational tasks in the network. The integrated system collects the advantages coming from logical reasoning and network programmability, and provides a powerful system capable of performing high-level management tasks in order to deal with network fault.

Plasmodiophora brassicae in its Environment

Plasmodiophora brassicae Wor. is viewed in this article from the standpoint of a highly evolved and successful organism, well fitted for the ecological niche that it occupies. Physical, chemical, and biological components of the soil environment are discussed in relation to their effects on the survival, growth, and reproduction of this microbe. It is evident that P. brassicae is well equipped by virtue of its robust resting spores for survival through many seasonal cycles. Germination is probably triggered as a result of signals initiated by root exudates. The resultant motile zoospore moves rapidly to the root hair surface and penetration and colonization follow. The short period between germination and penetration is one of greatest vulnerability for P. brassicae. In this phase survival is affected at the very least by soil texture and structure; its moisture; pH; calcium, boron, and nitrogen content; and the presence of active microbial antagonists. These factors influence the inoculum potential (sensu Garrett, 1956) and its viability and invasive capacity. There is evidence that these effects may also influence differentially the survival of some physiologic races of P. brassicae. Considering the interaction of P. brassicae with the soil environment from the perspective of its biological fitness is an unusual approach; most authors consider only the opportunities to destroy this organism. The approach adopted here is borne of several decades spent studying P. brassicae and the respect that has been engendered for it as a biological entity. This review stops at the point of penetration, although some of the implications of the environment for successful colonization are included because they form a continuum. Interactions with the molecular and biochemical cellular environment are considered in other sections in this special edition.

Carboxylate anions binding and sensing by a novel tetraazamacrocycle containing ferrocene as receptor

A tetraazamacrocycle containing ferrocene moieties has been synthesized and characterized. The tetraprotonated form of this compound was evaluated as a receptor (R) for anion recognition of several substrates (S), Cl-, PF6-, HSO4-, H2PO4- and carboxylates, such as p-nitrobenzoate (p-nbz(-)), phthalate (ph(2-)), isophthalate (iph(2-)) and dipicolinate (dipic(2-)). H-1 NMR titrations in CD3OD indicated that this receptor is not suitable for recognizing HSO4- and H2PO4-, but weakly binds p-nbz(-), and strongly interacts with ph(2-), dipic(2-), and iph(2-) anions forming 1 : 2 assembled species. The largest beta(2) binding constant was determined for ph(2-), followed by dipic(2-) and finally iph(2-). The effect of the anionic substrates on the electron-transfer process of the ferrocene units of R was evaluated using cyclic voltammetry (CV) and square wave voltammetry (SWV) in methanol solution and 0.1 mol dm(-3) (CH3)(4)NCl as the supporting electrolyte. Titrations of the receptor were undertaken by addition of anion solutions in their tetrabutylammonium or tetramethylammonium forms. The protonated ligand exhibits a reversible voltammogram, which shifts cathodically in the presence of the substrates. The data revealed kinetic constraints in the formation of the receptor/substrate entity for dipic(2-), ph(2-) and iph(2-) anions, but not for p-nbz(-). In spite of the slow kinetics of assembled species formation with the ph(2-) substrate, this anion provides the largest redox-response when the supramolecular entity is formed, followed by dipic(2-), iph(2-) and finally p-nbz(-) anions. This trend is in agreement with the H-1 NMR results and the values of the binding constants. Single crystal X-ray structures of the receptor with PF6-, ph(2-), iph(2-) and p-nbz(-) were carried out and showed that supermolecules with a RS2 stoichiometry are formed with the first three anions, but RS4 with p-nbz(-). In all cases the binding occurs outside the macrocyclic cavity via N-H center dot center dot center dot O=C hydrogen bonds for carboxylate anions and N - H center dot center dot center dot F hydrogen bonds for the PF6- anion, which is in agreement with the solution results. The macrocyclic framework adopts different conformations in order to interact with each substrate having Fe center dot center dot center dot Fe intramolecular distances ranging from 10.125(14) to 12.783(15) angstrom.

Degree of oxidation of low density lipoprotein affects expression of CD36 and PPAR gamma, but not cytokine production, by human monocyte-macrophages

Oxidized low-density lipoprotein (oxLDL) exhibits many atherogenic effects, including the promotion of monocyte recruitment to the arterial endothelium and the induction of scavenger receptor expression. However, while atherosclerosis involves chronic inflammation within the arterial intima, it is unclear whether oxLDL alone provides a direct inflammatory stimulus for monocyte-macrophages. Furthermore, oxLDL is not a single, well-defined entity, but has structural and physical properties which vary according to the degree of oxidation. We tested the hypothesis that the biological effects of oxLDL will vary according to its degree of oxidation and that some species of oxLDL will have atherogenic properties, while other species may be responsible for its inflammatory activity. The atherogenic and inflammatory properties of LDL oxidized to predetermined degrees (mild, moderate and extensive oxidation) were investigated in a single system using human monocyte-derived macrophages. Expression of CD36 mRNA was up-regulated by mildly- and moderately-oxLDL, but not highly-oxLDL. The expression of the transcription factor, proliferator-activated receptor-gamma (PPARgamma), which has been proposed to positively regulate the expression of CD36, was increased to the greatest degree by highly-oxLDL. However, the DNA binding activity of PPARgamma was increased only by mildly- and moderately-oxLDL. None of the oxLDL species appeared to be pro-inflammatory towards monocytes, either directly or indirectly through mediators derived from lymphocytes, regardless of the degree of oxidation.
