A regulação da atividade espacial

The technological evolution of the past fifty years has provided Humanity the contact with the last frontier of knowledge: space. An unknown world, explored by a small group of nations, which has become crucial to understanding who we are and where we come from. Space assets in recent years have opened the way to a digital society, shaped by the rapid exchange of information, whose means are mostly in space. A place of fascination and curiosity, restricted to a few people in these decades, which may soon be changing. This essay addresses some legal issues concerning the private exploration of space. Liability on space tourism is the core of this investigation, focusing on the comprehension of the international legal framework and its connection with the states national law. In particular, the study of the main international treaties, the U.S. legal system of space law and the developments in Europe are the fundamental tools of the current analysis, not forgetting the point of view of a possible international harmonization. Besides the needed theoretical context on the evolution of space law and a brief approach of the technical matters of the current aerospace engineering, the goal is to examine the characteristics of international space law and its relation with the new private actors, responsible for providing suborbital flights, operating in a near future. Within these circumstances, given the economic potential of the growing private space industry, it is essential to discuss the legal aspects of a spatial regulation. Being liability, undoubtedly, the emerging issue in the legal debate on this topic, it is important to safeguard the interests of the operators, States and, above all, future space tourists.

Relatório de estágio na Federação Portuguesa de Futebol

This report aims to present and describe in detail the internship held in the Legal Division of the Portuguese Football Federation (FPF) from February, 15th to June, 15th 2015, in order to obtain a Master degree in Law. This internship had, as prior objective, to understand the work of the Legal Division and what its role in the organizational structure of FPF. Initially, and in order to acquaintance with the greatest diversity possible of topics on which the Legal Division has to pronounce, we proceed with the analysis and resolution of several questions that have been presented to us. In a second phase, and after deepen the study of a particular subject - the Intermediate – we sought to clarify the procedure that needed to be adopted after the entry into force of the two new Regulations on the matter - the FIFA Regulations and the FPF Regulations. The transfer of the responsibility for regulation of this matter from FIFA to the National Federations, has raised a new challenge, which this report aims help solving, becoming a quasi-instruction manual on the procedures involving intermediaries, in order to facilitate the role of those involved.

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.

Regulação epigenética de um gene de resposta a stress de frio em arroz (OsDREB1B)

O arroz (Oryza sativa L.) constitui a principal fonte de alimento para mais de metade da população mundial. O frio tem um grande impacto no desenvolvimento da planta de arroz com efeitos negativos ao nível da produtividade e economia mundial. Os mecanismos epigenéticos associados a alterações estruturais da cromatina estão envolvidos nos mecanismos de resposta das plantas a stresses abióticos. O foco do presente trabalho consistiu na compreensão da influência de fatores epigenéticos, nomeadamente de modificações de histonas, na regulação transcricional de um gene específico (OsDREB1B) envolvido na resposta de arroz ao stress de frio. O estudo da regulação epigenética deste gene envolveu a utilização de plantas de arroz com mutações em enzimas epigenéticas e drogas remodeladoras da cromatina. Neste trabalho mostramos que o gene OsDREB1B é induzido pelo stress de frio (4 °C) em todas os genótipos de arroz analisados, no entanto, a indução do gene em resposta ao stress de frio é maior em Nipponbare que em Dongjin. Nos genótipos que apresentam epimutações, nomeadamente o knockout de osdrm2 (DMT706) e de oshac704 (HAC704), o gene OsDREB1B é mais expresso que no respetivo genótipo selvagem (Dongjin), sendo que a indução da expressão em resposta ao frio foi maior em DMT706 do que em HAC704. A análise do padrão de marcas histónicas ao longo do promotor de OsDREB1B, através da imunoprecipitação da cromatina (ChIP) com anticorpos específicos, revelou que, em resposta ao frio (4ºC), Dongjin apresenta uma menor predominância da marca H3K9ac na região de -519 a -355 pares de bases (antes do ATG), enquanto que Nipponbare possui maior presença de H4K5ac na região de -280 a -121 pares de bases, sugerindo que a regulação epigenética de OsDREB1B seja influenciada pelo genótipo. No caso dos epi-mutantes (HAC704 e DMT706) registou-se um empobrecimento das marcas histónicas testadas sugerindo que a indução da expressão do OsDREB1B em reposta ao stress provocado pelo frio não depende necessariamente da presença de OsDRM2 nem de OsHAC704. Uma visão integrada da paisagem epigenética e do transcriptoma, perspetiva uma melhor compreensão dos mecanismos envolvidos na resposta da planta a condições ambientais adversas, abrindo novas linhas de trabalho no sentido de obter plantas mais tolerantes a fatores de stress.

Os diferentes níveis de regulação legal dos conflitos de interesses no âmbito da gestão de fundos de investimento mobiliário

In the context of the activity developed by securities investment funds (hereinafter referred to “SIF”) the holders of investment units have a very tiny power to intervene. Aware of the risks that a decoupling between ownership and control may pose, the legislator has foreseen a number of impositions and limitations to the activity of the managing entities, namely to prevent or prohibit the performance of acts in situations of potential conflicts of interests. Accordingly, the purpose of the dissertation on – “Os diferentes níveis de regulação legal dos conflitos de interesses no âmbito da gestão de FIM” – is exactly to determine the field of application of the several levels of legal regulation of the conflicts of interests that arise within the scope of the management of SIF, both at the level of the new legal requirements governing collective investment undertakings, and at the level of the legal requirements governing the conflicts of interests foreseen in the Portuguese Securities Code, in order to clarify the articulation of these different levels of conflicts of interests regulations.

A liberalização do mercado energético e o papel das entidades reguladoras

The liberalisation of the energy market goes back to the 1990s, when it was impelled by the European legislator. Since then, three legislative packages, temporarily successive, were approved. Those packages contained the measures to be implemented in order to deepen the internal energy market. Besides the opening up of several national markets to competition, the European legislator aimed the creation of a real internal energy market within the European Union. The unbundling regime was one of the most important steps with respect to the liberalisation process. The introduction of these rules ensured independence to the various market operators. A real and effective right of choice was granted to the consumers so they may choose their electricity and natural gas supplier. Therefore, the activity of comercialisation is subject to competition. However, some activities of the electricity’s and natural gas’ chain of value, namely the activities of transportation and distribution, were kept under regulation rules. Even though it may seem odd, the assignment of important competences and strong powers to a regulatory authority was essential in order to achieve the liberalisation process’ goals. Electricity and natural gas are essential public goods; therefore the market operators are legally bound to public service obligations, such as the security, the universality and the continuity of the supply. The performance of these obligations may become, in some cases, unprofitable for those operators. For such reason, the protection of the consumers’ rights shall only be properly defended if there is a regulatory authority that monitors the behaviour of the operators and sanctions the failure to comply with the public service obligations. Portugal, as a Member State of the European Union, transposed into the national legal order the European directives concerning the liberalisation process. This transposition has caused radical changes to the electricity and natural gas’ national markets. The Entidade Reguladora dos Serviços Energéticos also suffered various mutations in order to keep up with the regulatory demands regarding the liberalisation process.

Perplexidades e incertezas da regulação dos media na Europa

A regulação dos media tem ganho relevo nas agendas nacionais e internacionais mas nem sempre a utilização corrente do conceito é consistente, correndo o risco de significar tudo e nada em simultâneo. Independentemente do intenso e profícuo debate concetual que o tema suscita na comunidade académica, julgamos pertinente o estudo das estruturas de regulação mediática que operam no terreno da União Europeia. Este trabalho reflete sobre as entidades de regulação mediática que atuam na defesa do interesse público, ainda que existam as mais diversas modalidades de enunciação e de defesa desse interesse pelos vários estados, e decorre de um esforço de investigação coletivo, enquadrado no projeto “Regulação dos Media em Portugal: O Caso da ERC”, que agregou elementos sobre os organismos reguladores dos media na Europa.

A impiedade das críticas ou a consciência da auto-regulação? O processo Casa Pia e o julgamento metajornalístico

(Excerto) Na sua justa e verdadeira atitude, o jornalismo aspira acima de tudo à procura do verdadeiro e do justo. É sua vocação primeira informar, revelar a genuinidade da vida. Mas a informação não existe jamais em si. Ela resulta, segundo Dominique Wolton, de uma construção de homens que tentam compreender o mundo para o dizer a outros homens. A informação funda-se, pois, no pressuposto de um poder, aparentemente exclusivo dos jornalistas: o poder de olhar o mundo e dizer dele o que se espera que todos devam saber. Este poder, que uns designaram por quarto (vigilante dos três poderes fundacionais do Estado democrático- liberal) e que outros3 entenderam sobrepor- se veemente às autoridades executiva, legislativa e judicial, é para Dominique Wolton a prova de que os jornalistas são os grandes vencedores do último meio século.
