[ES] El concepto de historia del patrimonio histórico-educativo ha ido cambiando acorde con la aparición de nuevas formas de comunicarnos. Hemos pasado de estar en archivos nacionales o autonómicos para conseguir documentos, a poder hacerlo desde la comodidad de nuestro hogar a través de unos simples clics. A pesar de ello, esta suerte de aventura sólo puede llevarse a buen término cuando aprendamos a ser investigadores-cernedores. Cuando aprendamos a separar con nuestro cedazo la información veraz, presumible de poder erigirse en conocimiento científico, de aquella infoxicada que distorsiona y llena de ruidos nuestras pesquisas como personas historiadoras.

O estudo procuratraçar os contornos gerais do direito ao esquecimento no ordenamento jurídico brasileiro. O direito ao esquecimento consiste em um instrumento eficaz para impedir que a divulgação de fatos passados, destituídos de relevância informativa, venham a impedir o livre desenvolvimento da pessoa humana, na realização autônoma de seu projeto de vida. Apesar de poder ser exercido por qualquer indivíduo, independentemente de sua notoriedade, o direito ao esquecimento não é absoluto edeve ser ponderado com os direitos potencialmente conflitantes, como a liberdade de expressão e direito à informação.Para melhor compreensão dessa difícil ponderação são apresentados os critérios utilizados pela jurisprudência nacional e estrangeira na solução do árduo conflito entre a divulgação das informações e o direito ao esquecimento, em cujo contexto a atualidade da informação emerge como critério preponderante, embora não absoluto, já que fatos de relevância histórica também merecem proteção jurídica. A questão é igualmente examinada no ambiente virtual, a fim de que sejam identificadas as diversas formas de esquecimento na internet, as quais encontram outros meios de efetivação não se restringindo à possibilidade de apagar informações.

Research in inclusive design has shown the importance of prior experience for the usability of interactive products. Prior experience, however, is an ill-defined and inconsistently used construct. A number of different definitions and operationalisations of experience exist, but the differing power of these operationalisations to predict the usability of products for older users has rarely been investigated systematically. This study seeks to fill that gap. It is argued that the construct of experience has at least three components. It is proposed that two of these components, exposure and competence, are directly relevant for the current discussion about prior experience in inclusive design and that they can predict to different degrees the usability of a product for older users. In an empirical study, these facets of expertise are each operationalised on three levels of specificity and their impact on usability is assessed. The results show that measures of competence predict usability variables more strongly than measures of exposure and that levels of medium and high specificity are the best predictors. The application of inclusive design principles to a redesigned version of a ticket vending machine-although not resulting in a difference of overall usability-changed the impact of prior experience on usability measures implying an enhanced inclusiveness of the redesign with regard to prior experience. The implications of these findings for the effectiveness of inclusive design for older users are discussed. © 2013 Springer-Verlag Berlin Heidelberg.

The digital divide has been, at least until very recently, a major theme in policy as well as interdisciplinary academic circles across the world, as well as at a collective global level, as attested by the World Summit on the Information Society. Numerous research papers and volumes have attempted to conceptualise the digital divide and to offer reasoned prescriptive and normative responses. What has been lacking in many of these studies, it is submitted, is a rigorous negotiation of moral and political philosophy, the result being a failure to situate the digital divide - or rather, more widely, information imbalances - in a holistic understanding of social structures of power and wealth. In practice, prescriptive offerings have been little more than philanthropic in tendency, whether private or corporate philanthropy. Instead, a theory of distributive justice is required, one that recovers the tradition of emancipatory, democratic struggle. This much has been said before. What is new here, however, is that the paper suggests a specific formula, the Rawls-Tawney theorem, as a solution at the level of analytical moral-political philosophy. Building on the work of John Rawls and R. H. Tawney, this avoids both the Charybdis of Marxism and the Scylla of liberalism. It delineates some of the details of the meaning of social justice in the information age. Promulgating a conception of isonomia, which while egalitarian eschews arithmetic equality (the equality of misery), the paper hopes to contribute to the emerging ideal of communicative justice in the media-saturated, post-industrial epoch.

W ciągu minionych trzech dekad świat radykalnie się zmienił. Jesteśmy świadkami transformacji od społeczeństwa przemysłowego do społeczeństwa informacyjnego. Jeśli chcielibyśmy określić tą zmianę jednym słowem byłoby nim: cyfryzacja. Początkiem było wynalezienie cyfrowego komputera, a później wszystkie stare analogowe formy medialne (tekst, dźwięk, obraz, film) reprezentowane poprzez ciągłe (analogowe) sygnały zostały zastąpione przez nowe postaci cyfrowe. Pojęcie cyfrowy oznacza, że dowolne informacje mogą być reprezentowana w formie ciągów liczb zapisanych w dwójkowym systemie liczbowym (jako ciąg znaków: 0 i 1). W artykule pokazujemy funkcjonalne ograniczenia mediów analogowych oraz rozważamy korzyści wynikające z cyfrowych reprezentacji różnych form informacji wskazując równocześnie zmiany jakie implikuje to dla procesu uczenia się i edukacji.

Administracja publiczna, ze względu na swoją istotę (służbę), musi spełniać oczekiwania społeczne, stąd oprócz modernizacji zasobów, reorganizacji należy także modyfikować jej mentalność. Inaczej bez systematycznego dostosowywania się do jakże dynamicznej rzeczywistości zawiedzie i przeistoczy się w dysfunkcjonalną strukturę. W społeczeństwie ryzyka, w społeczeństwie informacyjnym, a takim niewątpliwie jesteśmy, newralgicznym elementem, szczególnie w sytuacjach kryzysowych, stała się polityka informacyjna. Warto zatem scharakteryzować jej istotę i wpływ na otoczenie, by następnie podmiotom zainteresowanym bezpieczeństwem przedstawić dostosowawcze rekomendacje o kluczowym znaczeniu. Należy pamiętać, że zdecydowana większość społeczeństwa ocenia rzeczywistość na podstawie wyrywkowych informacji z mass mediów, niż na szczegółowej analizie działalności administracji publicznej.
