The CARIFORUM-EU Economic Partnership Agreement (EPA): an assessment of issues relating to market access, safeguards and implications for regional integration

The recent collapse of the Doha round once again underscores the tenuous nature of international trade negotiations. Likewise, the Economic Partnership Agreement (EPA) between the CARIFORUM grouping and the European Union (EU) has generated a great deal of discussion and debate over the past several months. What has clearly emerged is the existence of two diametrically opposed views on the impact and usefulness of the agreement. One view has it that the EPA is a major breakthrough in trade relations that will greatly benefit the region. On the other hand, some see it as being detrimental to the region and perhaps a total capitulation to the EU on the part of the CARIFORUM. They assert that it is part of a global EU strategy to impose World Trade Organization (WTO) policies on developing nations and get around the Doha obstacles. Both sides in this debate attempt to back up their views with reference to the text of the agreement. The objective of this review is to shed some light on the issues driving this debate particularly in the areas of market access, the impact on tariff revenues, and the implications for regional integration. This review also attempts to clarify and distill some of the main contentious issues regarding the EPA and to inform further discussion regarding an implementation plan. The approach is based on detailed study of the EPA text and its annexes plus extensive interviews with some of the main negotiators on the CARIFORUM side. Interviews were conducted both in person and via the Internet as many of the regional negotiators live or work outside of the region. The reviewer also attended presentations and discussions with some of the leading regional critics of the agreement.

The new digital revolution: From the consumer Internet to the industrial Internet

The new digital technologies have led to widespread use of cloud computing, recognition of the potential of big data analytics, and significant progress in aspects of the Internet of Things, such as home automation, smart cities and grids and digital manufacturing. In addition to closing gaps in respect of the basic necessities of access and usage, now the conditions must be established for using the new platforms and finding ways to participate actively in the creation of content and even new applications and platforms. This message runs through the three chapters of this book. Chapter I presents the main features of the digital revolution, emphasizing that today’s world economy is a digital economy. Chapter II examines the region’s strengths and weaknesses with respect to digital access and consumption. Chapter III reviews the main policy debates and urges countries to take a more proactive approach towards, for example, regulation, network neutrality and combating cybercrime. The conclusion highlights two crucial elements: first, the need to take steps towards a single regional digital market that can compete in a world of global platforms by tapping the benefits of economies of scale and developing network economies; and second, the significance of the next stage of the digital agenda for Latin America and the Caribbean (eLAC2018), which will embody the latest updates to a cooperation strategy that has been in place for over a decade.

Fanfictions na Internet - um clique na construção do leitor-autor

Esta dissertação trata do fenômeno da autoria na internet, tendo como foco de estudo do leitor-autor, mais especificamente, de um autor que foi uma vez leitor de uma história original e que assume a função de continuar a história (do ponto em que a deixou seu primeiro criador) ou de modificá-la de forma a agradar a si mesmo e/ou a outros leitores eventuais. Conforme uma vez afirmou Roland Barthes (2004), o escritor sempre será um imitador de escritos anteriores à sua época, mas nunca original. A partir de análises de trechos das histórias, suas notas de autoria e interação com outros leitores através dos comentários, essas criações de fãs-autores (como são chamados nessa pesquisa os autores que se dedicam à escrita desse tipo de história), estuda-se a modificação do conceito de autoria na atualidade, pois muitas vezes o autor perde seu posto ao manter contato com alguma forma de tecnologia da informação – e agora lida com gêneros chamados híbridos: textos que não são puros, que não possuem uma característica apenas para poderem ser definidos pelos manuais comuns. Desta forma é difícil definir o que é, afinal, o autor na era dos gêneros digitais. Num momento em que a cada dia as pessoas do mundo inteiro aumentam seu número de horas navegando, os gêneros digitais representam uma nova relação entre ser humano e instrumento semiótico, com diversos aspectos a serem observados.

Predição de qualidade de experiência para internet do futuro em arquiteturas heterogêneas de redes sem fio móveis

As Redes da Próxima Geração consistem no desenvolvimento de arquiteturas que viabilizem a continuidade de serviços que proporcionem sempre a melhor conectividade (Always Best Connectivity - ABC) aos usuários móveis com suporte adequado à Qualidade de Experiência (QoE) para aplicações multimídia de alta definição, nesse novo contexto as arquiteturas têm perspectiva orientada a serviços e não a protocolos. Esta tese apresenta uma arquitetura para redes da próxima geração capaz de fornecer acesso heterogêneo sem fio e handover vertical transparente para as aplicações multimídia. A tese considera diferentes tecnologias sem fio e também adota o padrão IEEE 802.21 (Media Independent Handover – MIH) para auxiliar na integração e gerenciamento das redes heterogêneas sem fio. As tecnologias que a arquitetura possui são: IEEE 802.11 (popularmente denominada de WiFi), IEEE 802.16 (popularmente denominada de WiMAX) e LTE (popularmente denominada de redes 4G). O objetivo é que arquitetura tenha a capacidade de escolher entre as alternativas disponíveis a melhor conexão para o momento. A arquitetura proposta apresenta mecanismos de predição de Qualidade de Experiência (Quality of Experience - QoE) que será o parâmetro decisivo para a realização ou não do handover para uma nova rede. A predição para determinar se haverá ou não mudança de conectividade será feita com o uso da inteligência computacional de Redes Neurais Artificiais. Além disso a arquitetura também apresenta um mecanismo de descarte seletivo de pacotes especifico para aplicações multimídia. A proposta é avaliada via simulação utilizando-se o ns-2 (Network Simulator) e os resultados de desempenho são apresentados através das métricas de QoS, de QoE e também visualmente através da exibição de frames dos vídeos transmitidos na arquitetura.

Information access law and disclosing of information by joint-stock companies in Brazil: open data and Extensible Business Reporting Language (XBRL) standard

The strategic management of information plays a fundamental role in the organizational management process since the decision-making process depend on the need for survival in a highly competitive market. Companies are constantly concerned about information transparency and good practices of corporate governance (CG) which, in turn, directs relations between the controlling power of the company and investors. In this context, this article presents the relationship between the disclosing of information of joint-stock companies by means of using XBRL, the open data model adopted by the Brazilian government, a model that boosted the publication of Information Access Law (Lei de Acesso à Informação), nº 12,527 of 18 November 2011. Information access should be permeated by a mediation policy in order to subsidize the knowledge construction and decision-making of investors. The XBRL is the main model for the publishing of financial information. The use of XBRL by means of new semantic standard created for Linked Data, strengthens the information dissemination, as well as creates analysis mechanisms and cross-referencing of data with different open databases available on the Internet, providing added value to the data/information accessed by civil society.

Redes sociais na Internet: uma investigação sobre práticas de compartilhamento de arquivos no Facebook

The social networking sites have experienced a large and rapid growth in recent years and bring together millions of users in Brazil and worldwide. Such networks allow adding groups of people with common interests or relationships, enabling members of this group to communicate and exchange information. Some social networks have specific goals, for example, aggregate individuals with common interests and professional relationships. However, they all share information in some way, whether in the form of short texts, photos, videos, among others. Sharing information in files is also a growing activity on the Internet and can be done in various ways, from sending files via email to multiple contacts to make available areas shared by the same contacts. However, applications are not yet available to enable file sharing on Facebook, considered the premier social network today. Given the growing demand for sharing files over the Internet, and a large number of users familiar with the use of these integrated applications for Facebook there is a demand for applications that allow users to share files with their contacts in this social network. This study aims to investigate how users use Facebook, and their practices for file sharing. It is believed that the results will substantiate future projects to develop software for file sharing on Facebook. Due to the exploratory nature of this research, the choice was made for a survey to collect data, applied through the web. From the results obtained, was possible to observe a frequent use of file sharing, but no interest in paid services. Regarding Facebook, was possible to observe their extensive use in both the frequency of access as the hours spent, as well as an increased use of applications (games, quiz, etc.). The full set of results shows a favorable environment for developing applications for sharing files on Facebook.

Optical Communication Networks for the Next-Generation Internet

Computer and telecommunication networks are changing the world dramatically and will continue to do so in the foreseeable future. The Internet, primarily based on packet switches, provides very flexible data services such as e-mail and access to the World Wide Web. The Internet is a variable-delay, variable- bandwidth network that provides no guarantee on quality of service (QoS) in its initial phase. New services are being added to the pure data delivery framework of yesterday. Such high demands on capacity could lead to a “bandwidth crunch” at the core wide-area network, resulting in degradation of service quality. Fortunately, technological innovations have emerged which can provide relief to the end user to overcome the Internet’s well-known delay and bandwidth limitations. At the physical layer, a major overhaul of existing networks has been envisaged from electronic media (e.g., twisted pair and cable) to optical fibers - in wide-area, metropolitan-area, and even local-area settings. In order to exploit the immense bandwidth potential of optical fiber, interesting multiplexing techniques have been developed over the years.
