A internet e o sistema de justiça

The subject of study of this Thesis aims to highlight and recognize as an object of reflection the undoubted relationship between the Internet and the Justice System, based on the issue of digital evidence. The simultaneously crossing of the juridical-legal implications and the more technical computer issues is the actual trigger for the discussion of the issues established. The Convention on Cybercrime of the Council of Europe of 23rd November 2001 and the Council Framework Decision n.° 2005/222/JHA of 24th February 2005 were avant-garde in terms of the international work about the crimes in the digital environment. In addition they enabled the harmonization of national legislations on the matter and, consequently, a greater flexibility in international judicial cooperation. Portugal, in compliance with these international studies, ratified, implemented and approved Law n. º 109/2009 of 15th September concerning the Cybercrime Act, establishing a more specific investigation and collection of evidence in electronic support when it comes to combating this type of crime, as it reinforced the Substantive Criminal Law and Procedural Nature. Nevertheless, the constant debates about the New Technologies of Information and Communication have not neglected the positive role of these tools for the user. However, they express a particular concern for their counterproductive effects; a special caution prevails on the part of the judge in assessing the digital evidence, especially circumstantial evidence, due to the its fragility. Indisputably, the practice of crimes through the computer universe, given its inexorable technical complexity, entails many difficulties for the forensic investigation, since the proofs hold temporary, changeable, volatile, and dispersed features. In this pillar, after the consummation of iter criminis, the Fundamental Rights of the suspects may be debated in the course of the investigation and the construction of iter probatorium. The intent of this Thesis is to contribute in a reflective way on the issues presented in order to achieve a bigger technical and legal awareness regarding the collection of digital proof, looking for a much lighter approach to its suitability in terms of evidentiary value.

Les droits économiques dans l'environnement numérique : portrait de notions en mutation

L'accès généralisé à Internet a remis en question le droit d'auteur. Au milieu des années 90, il s'en trouvait plusieurs pour annoncer la mort de cette institution vieille de quelques siècles. Force est aujourd'hui de constater que le droit d'auteur est toujours bien vivant bien qu'il ait changé. Les droits économiques, qui ont rapidement été appliqués dans l'environnement numérique, témoignent de ces changements. L'analyse de la transmission numérique des fichiers audio expose les mutations qui affectent deux droits économiques en particulier: le droit de reproduction et le droit de communication au public par télécommunication. Ces mutations résultent tantôt de l'intervention du législateur, tantôt de la façon dont on choisit d'appliquer ces droits dans ce nouvel environnement. Elles ont souvent pour effet d'étendre la portée traditionnelle de ces droits économiques. Cela se fait parfois au détriment des rationalités qui en justifient l'existence. De plus, la nouvelle interaction entre ces droits mutés entraîne des effets sur les différents acteurs du droit d'auteur qui sont parfois discutables. Le droit d'auteur a toujours sa raison d'être. Reste à savoir si la forme actuelle des droits économiques est toujours le meilleur véhicule pour atteindre les objectifs sous-jacents. À l'heure où le législateur envisage une simplification du droit d'auteur, une réflexion s'impose au sujet de la forme des droits économiques. Il est grand temps, du moins dans l'environnement numérique, d'adopter une approche qui se fonde plus sur les effets des actes posés que sur leur nature. L'examen des mutations qui affectent les droits économiques dans cet environnement fait d'ailleurs prendre conscience des limites de notre façon positiviste d'envisager ces droits.

Online Dispute Resolution: The Next Phase

Ce texte traite de l’évolution des modes alternatifs de résolution de conflit (MARC) en ligne. L’auteur dresse un historique des différents projets de médiation en ligne en passant par ses « débuts » en 1999 lorsque l’Online Ombuds Office (OOO) fut approché pour l’élaboration d’un système de médiation pour les clients d’eBay, par SquareTrade.com, par les règles de l’ICANN, par Cybersettle et Clicknsettle, etc. Il expose ensuite le courrant que prendra la cybermédiation et le cyberarbitrage dans les années à venir. Ainsi, le médium informatique devient lentement une « quatrième partie » aux discussions et peut venir en aide aux arbitres et aux médiateurs dans la gestion et la communication d’informations. De plus les fonctions d’affichages propres aux ordinateurs, c’est-à-dire la possibilité d’incorporer images, graphiques, plans, etc., devront être mis à l’œuvre par les systèmes de MARC en ligne si ceux-ci sont destinés à prendre de l’expansion dans d’autres domaines que ceux leur étant présentement réservés.

What is editorialization?

Cet article présente les résultats de huit ans de travail sur le concept d’éditorialisation, réalisés dans le cadre du séminaire international « Écritures numériques et éditorialisation » que j’ai coorganisé avec Nicolas Sauret depuis 2008. Je propose de définir l’éditorialisation comme l’ensemble des dynamiques qui produisent l’espace numérique. Ces dynamiques peuvent être comprises comme les interactions d’actions individuelles et collectives avec un environnement numérique. À partir de cette définition je propose de décrire le fonctionnement des instances d’autorité dans l’espace numérique.

The Role of the online learner: onsite students becoming online learners

As universities are offering tuition through online learning environments, “onsite students” in higher education are increasingly becoming “online learners”. Since the medium for learning (and teaching) online is a digital environment, and at a distance, the role taken by students and teaching staff is different to the one these are used to in onsite, traditional settings. Therefore the Role of the Online Learner, presented in this paper, is key to onsite students who are to become online learners. This role consists of five competences: Operational, Cognitive, Collaborative, Self-directing, Course-specific. These five competences integrate the various skills, strategies, attitudes and awareness that make up the role of online learner, which learners use to perform efficiently online. They also make up the basis of a tutorial for would-be online learners, going over the Role of the Online Learner by means of concepts, examples and reflective activities. This tutorial, available to students in the author’s website, is also helpful to teaching and counselling staff in guiding their students to become online learners

Continuous prewarping of time for multiuser interactive virtual environments

Dynamic multi-user interactions in a single networked virtual environment suffer from abrupt state transition problems due to communication delays arising from network latency--an action by one user only becoming apparent to another user after the communication delay. This results in a temporal suspension of the environment for the duration of the delay--the virtual world `hangs'--followed by an abrupt jump to make up for the time lost due to the delay so that the current state of the virtual world is displayed. These discontinuities appear unnatural and disconcerting to the users. This paper proposes a novel method of warping times associated with users to ensure that each user views a continuous version of the virtual world, such that no hangs or jumps occur despite other user interactions. Objects passed between users within the environment are parameterized, not by real time, but by a virtual local time, generated by continuously warping real time. This virtual time periodically realigns itself with real time as the virtual environment evolves. The concept of a local user dynamically warping the local time is also introduced. As a result, the users are shielded from viewing discontinuities within their virtual worlds, consequently enhancing the realism of the virtual environment.

As redes sociais virtuais: motivos para a utilização pelas organizações no Brasil

Esse estudo objetiva compreender porque as empresas, no Brasil, decidem investir em redes sociais na internet. Foram considerados fatores como a evolução da internet e das próprias redes sociais interativas (em especial Twitter, Facebook e YouTube), as rápidas mudanças tecnológicas que ocorrem no ambiente digital e o papel das agências de comunicação no mercado virtual. Nesse contexto, foi possível observar a importância das redes sociais, atualmente, no negócio das empresas. A falta de material acadêmico sobre o assunto fez com que a visita e a coleta de materiais em diversos websites fossem um recurso complementar valioso. Adicionalmente, com o foco no cenário brasileiro, foram realizadas entrevistas qualitativas semiestruturadas, com 11 gestores de empresas e três gestores de agências de comunicação, o que propiciou um mapeamento das motivações para a utilização das redes sociais pelas empresas, assim como o levantamento de outras informações valiosas para esse trabalho. O referencial teórico buscou contextualizar um panorama privilegiado nesse estudo, considerando o ambiente dinâmico da internet, as redes sociais interativas e seu valor, a mobilidade de acesso, e as agências de publicidade e redes sociais. Além dos resultados apresentados nesse estudo, as revelações de campo e suas discussões propiciaram a elaboração de uma tabela de grau de maturidade social em relação ao momento em que as empresas estão no âmbito digital, assim como o desenvolvimento de um modelo de aprendizagem organizacional no ambiente virtual para redes sociais. Finalmente, foram apresentadas as conclusões, assim como as considerações finais. O estudo demonstrou a importância das redes sociais no cotidiano das empresas e a necessidade de estarem presentes no ambiente virtual, já que estão nesse universo mesmo que de maneira passiva. Embora não tenha havido um fator genérico que possa ser utilizado como padrão motivacional para o investimento inicial nas redes sociais, a visibilidade da exposição da marca nesse meio, seguida pela necessidade de criar um canal de relacionamento com o cliente destacaram-se como fatores motivacionais mais relevantes para esse movimento.

Impactos da adoção da INTERNET na hotelaria : a percepção dos gerentes de hotéis de médio e grande porte de Natal / RN

The hotel industry is increasingly using the Internet like a management and operational tool. That way, the hotels will be more prepared to offer quality services to their guests and increase their profits as well. However, many managers seem don t perceive the advantages brought from this new digital environment. This thesis analyse the effects of the hotel managers perceptions as for the Internet effectiveness, Internet access, Internet as a communication tool, future importance of the Internet, benefits and drawbacks of the Internet, according to property type (simple, medium comfort and luxe), property size (quantity of the apartaments), age and hotel industry experience of the managers. The methodology utilized was a survey about the hotels that had at least 40 apartments (medium and big property size), were working in Natal-RN and classified in categories in the Guia Quatro Rodas Brasil, totalizing 35 hotels. Through the analysis of variance (ANOVA) and Tukey test, the results showed that the hotel managers with more than 50 apartments, the managers of the hotel more comfortable, the younger managers and the managers less experient in the hotel industry, demonstrated more conscious about the importance of the adoption of the Internet than the rest of the others. The contribution of this work is to offer more knowledge to the hotel executives about how they can use the Internet and show the importance of the web adoption in their properties
