Gestão eficiente da energia eléctrica no edifício da Biblioteca da FCT e negociação de um novo contrato em mercado liberalizado

Nos últimos anos, a energia eléctrica tem vindo a conquistar, um lugar cada vez mais importante na sociedade, sendo nos nossos dias um bem essencial para o funcionamento normal das residências, empresas, indústrias e cidades. O problema que a presente dissertação analisa é transversal a inúmeros edifícios, que consomem diariamente uma grande quantidade de energia eléctrica, na ordem dos 900 kWh diários, ou mesmo superior. Desta forma, considera-se o consumo de eletricidade, e potenciais ineficiências no seu uso, num edifício universitário, nomeadamente a biblioteca da Faculdade de Ciências e Tecnologia (FCT) da Universidade Nova de Lisboa (UNL). Em termos mais específicos, pretende-se definir um consumo de energia mais eficiente, deslocando consumos de uns períodos horários para outros, onde as tarifas sejam mais económicas, aplicando medidas de participação ativa dos consumidores (PAC). Além disso, pretende-se simular a negociação de um novo contrato bilateral, entre um retalhista e um agente “gestor” da biblioteca da FCT, para obter um contrato melhorado, do ponto de vista do consumidor. Os principais objetivos desta dissertação são, deste modo, os seguintes: (i) estudar a contratação bilateral de energia em mercados liberalizados, com principal ênfase para a implementação de estratégias de negociação que possibilitem uma participação ativa dos consumidores, (ii) estudar a biblioteca da FCT e propor medidas de eficiência energética, e (iii) simular a negociação de um novo contrato bilateral, recorrendo ao simulador multi-agente MAN-REM. De forma sucinta, os resultados obtidos, permitem concluir que o consumo energético da biblioteca da FCT pode ser melhorado, e com base nos volumes de energia deduzidos, é possível negociar um novo contrato, mais favorável à FCT.

A protecção jurídica do consumidor em Angola

The scope of the present work is to study the legal protection conferred upon the consumer in Angola, especially as regards electronic communication agreements. Its purpose is to promote consumers’ rights and contribute to its defence given the relatively privileged position of professionals in their relationship with consumers. With this in mind, we have made a description of the Consumer Law in Angola based on the Angolan Constitution (as the law that establishes the fundamental rights and guarantees of citizens) and on the Consumer’s Defence Law, which, as the basic law regarding consumers’ rights, provides the framework for this dissertation. We have analysed several aspects relating to consumer relationships, starting from its concept and rights of consumers and covering the legal and contractual mechanisms put in place for their protection. We have also analysed the Advertising Law with a view to better understand consumer’s rights before advertising campaigns carried out by professionals whilst promoting their goods and services and, additionally, to understand the duties and principles that shall be complied with in such campaigns with the purpose to protect the rights and interests of consumers. From a criminal point of view, we have briefly covered the crimes against consumers provided for in the Penal Code and the Law of Infractions against the Economy. In the second part of this work, we have summarised the institutions that protect the rights and interests of consumers, which include the Public Prosecutor Office, the National Institute for the Defence of the Consumers and the Consumers’ Associations. The third and last part of this work covers electronic communications agreements. Given the fact that there is no specific legislation in this matter, our analysis was based on the Civil Code – specifically the part relating to contracts – the Law on General Contractual Terms and Conditions and the Consumer’s Defence Law. We have analysed the formation of contracts, compliance and consumers’ rights resulting from contract breach. We further have appealed to the Angolan legislator to legislate certain aspects of consumer relationships, especially those where breach of consumers’ rights are blatant and facilitated by the lack of specific laws addressing such cases.

Arbitragem de consumo no direito brasileiro

This dissertation analyzes how the current Constitution and the Brazilian law establish consumer protection, arbitration and access to justice. Following we try to demonstrate why arbitration is a method rarely used in the resolution of consumer disputes in Brazil. It also examines the doctrinal and jurisprudential aspects of the conflict between the Brazilian Arbitration Law (Law nº. 9.307/96), which allows the arbitration clause in contracts of adhesion, and the Consumer Protection Code (Law nº 8.078/90) that in article 51, VII, considers as abusive the arbitration clause. Furthermore, analyzes new proposed bills under scrutiny by the National Congress on the issue and identifies the causes, in the Brazilian legal system, hampering the use of arbitration in consumer relations. Concludes that there are no principle obstacles preventing consumer litigations to be settled by arbitration. High costs, mistrust, oppression, misinformation of consumers and non-participation of the State, being a totally private institute, are factors that generate distrust, suspicion, and have prevented the development of arbitration in consumer relations in Brazil.

Contrato de abertura de crédito bancário

La recherche que nous avons mené à bien avait pour but, dans un premier temps de comprendre la notion de contrat, ses caractéristiques, fonctions et les garanties qui en peuvent être fournies. Nous invoquerons le contenu du contrat, c'est à dire, les effets de celui-ci en essayant de montrer les droits et obligations auxquels les parties seront liées. Bien qu'étant un contrat assez requérant dans la pratique bancaire, celui-ci n'a pas encore attiré l'attention du législateur de façon à établir un régime qui pourrait lui être appliqué au lieu de s'appuyer sur d'autres contrats lui étant similaires. Nous proposons l'analyse de la cessation du contrat, en se concentrant sur les moyens de la dissolution, survenue suite à la conclusion de l'accord comme la plainte, l'abrogation, l'expiration et la résolution du contrat, en laissant de côté la dissolution du contrat pour des raisons survenues avant la conclusion du contrat, comme la nullité et l'annulation.

Conselho de Resolução de Litígios

The scope of the following study is to present an alternative and preventive dispute resolution method known as Dispute Resolution Board. The Dispute Resolution Board mechanism is included in construction contracts to support project participants in avoiding and resolving disputes. Over the years the construction industry dealt with the resolution of claims and disputes through several methods. One of the most successful and lasting is the Dispute Resolution Board. A Dispute Resolution Board is a board of impartial professionals formed at the start of the project to follow construction progress, prevent arising disputes, and assist in the resolution of disputes during the project. When a dispute arises the Board meets with the parties to settle this dispute. The recommendation of this Board is non-binding for the parties. In Portugal there is no experience with this form of conciliation.

Kixikila - um contrato de financiamento informal

The purpose of the present work is to analyse and provide kixikila legal framework under Angolan law. Kixikila, despite being a legally atypical agreement, is a socially typical contract, governed essentially by the practices and customs in Angola and concluded throughout the country. With the above purpose in mind, this thesis is structured in five chapters: the first one aims at better understanding its features and, therefore, it describes the kixikila in accordance with oral research, direct observation and the contributions of scholars that have examined this matter. The second chapter aims at qualifying the kixikila as a legal transaction. For this purpose, we have analysed its requirements, formation stages, content and form, characteristics, rights and obligations of the parties, effects and compliance. We have also covered the reasons that explain why this type of agreement shall be legally protected in line with the protection conferred upon other legal agreements, taking into account its economic and social function. The third chapter covers the vicissitudes which may occur during the term of the kixikila agreement, as well as the enforcement mechanisms in face of breach and its termination. The fourth chapter aims at qualifying this agreement by comparing its most relevant characteristics with those of typical agreements, with a view to determining its legal nature based upon the similarity with other contractual types. This chapter further makes a comparative synthesis between the contracts in analysis. The fifth chapter analyses the legal nature and legal framework applicable to kixikila taking into account mixed-purpose contracts and sui generis contracts. We conclude that practices and customs in Angola take precedence as regards kixikila. Lastly, we attach additional information, such as excerpts of interviews with some individuals intervening in kixikila, the functional structure of kixikila and examples of kixikila, as well as demonstrative lists of countries where this type of agreement takes place and the obligations arising therefrom.

Variación florística de especies arbóreas a escala local en un bosque de tierra firme en la Amazonia colombiana

El presente estudio se llevó a cabo en cinco hectáreas de una parcela permanente establecida en el Parque Nacional Amacayacu, Amazonia colombiana. En éste, se evaluó el efecto de la variación ambiental y la configuración espacial sobre los patrones florísticos de las especies arbóreas (DAP>10 cm) a escala local en un bosque de tierra firme. Se estudió la variación florística y ambiental en cuadrantes de 20x20 m. Adicionalmente, se consideraron diferentes categorías de abundancia (total, alta, media y baja). Se utilizó el Análisis de Correspondencia Linealizado y el Análisis de Correspondencia Canónica, seguido de una partición de la variación, para cuantificar la magnitud a la cual el ambiente y la limitación en dispersión determinan la variación florística. La fracción espacial, representando procesos de autocorrelación como la limitación en dispersión, se analizó mediante dos métodos: Asumiendo un polinomio de tercer grado y por el método de Coordenadas Principales de Matrices Vecinas (PCNM). La diversidad beta de la parcela fue baja. El PCNM aparece como el método de análisis más apropiado para estudios a esta escala. Las diferencias florísticas explicadas a lo largo de la parcela de 5-ha fueron principalmente asociadas con procesos biológicos como la limitación en dispersión. La mayor parte de la variación florística, no obstante, no fue explicada por las variables ambientales o espaciales consideradas. En conclusión, estos resultados sugieren que procesos aleatorios son determinantes esenciales de la variación espacial de las especies arbóreas a escala local en tierra firme en los bosques en el Parque Nacional Amacayacu.
