Successful computer-supported distance education requires that its enabling technologies are accessible and usable anywhere. They should work seamlessly inside and outside the information superhighway, wherever the target learners are located, without obtruding on the learning activity. It has long been recognised that the usability of interactive computer systems is inversely related to the visibility of the implementing technologies. Reducing the visibility of technology is especially challenging in the area of online language learning systems, which require high levels of interactivity and communication along multiple dimensions such as speaking, listening, reading and writing. In this article, the authors review the concept of invisibility as it applies to the design of interactive technologies and appliances. They describe a specialised appliance matched to the requirements for distance second language learning, and report on a successful multi-phase evaluation process, including initial field testing at a Thai open university.

Social Work Education and Training in Europe and the Bologna Process

A short review of the last three decades shows that social work programmes have developed similarly in (almost) all European countries, both in terms of structural and content-related characteristics. Here I would like to focus on the following aspects: Increased academic focus of training, Generalist programme, International/European orientation. Increased academic focus means that social work programmes have been established at uni-versities or comparable higher education institutions, such as universities of applied sciences. The only exception is France where the approximately 150, generally fairly small colleges and the 14 larger instituts regionaux have a hybrid position between vocational colleges and universities and are roughly comparable to academies.

Zur Inhaltsstruktur von Rechtsnormen: Modalitäten und Normtypen

Rechtsnormen als Texte – Versuch einer Zusammenführung von Rechtstheorie und Linguistik: Rechtstheoretiker sind sich zwar bewusst, dass Recht wesentlich Sprache ist; diese Voraussetzung wird aber in der konkreten Analyse von Rechtsnormen und ihrer Struktur nur selten systematisch berücksichtigt; zumeist wird von der konkreten sprachlichen Form abgesehen oder der einzelne Satz wird als formale Größe absolut gesetzt. Dazu werden auch meist wichtige Erkenntnisse der Linguistik kaum berücksichtigt, etwa grundlegende Differenzierungen wie jene zwischen Satz und Text bzw. Grammatik und Äußerung oder Ausdruck und Inhalt. Dieser Beitrag versucht, Rechtsnormen als geschriebene Texte sui generis, d. h. als sprachliche Objekte, ernst zu nehmen und aus einem textlinguistischen Blickwinkel zu betrachten, durchaus im Horizont der Rechtstheorie und deren Erkenntnisinteresse, und die grundlegenden Eigenschaften von Rechtsnormen aus dieser zweifachen Perspektive deutlicher zu klären, etwa in Bezug auf die innere Struktur von Rechtsnormen, auf eine Typologie von Rechtsnormen, die Bedeutung von einzelnen Normen, das Verhältnis von innerer Struktur und äusserer Form oder die Adressatenfrage.

Cut Out By The Middle Man: The Free Speech Implications Of Social Network Blocking and Banning In The EU

This article examines social network users’ legal defences against content removal under the EU and ECHR frameworks, and their implications for the effective exercise of free speech online. A review of the Terms of Use and content moderation policies of two major social network services, Facebook and Twitter, shows that end users are unlikely to have a contractual defence against content removal. Under the EU and ECHR frameworks, they may demand the observance of free speech principles in state-issued blocking orders and their implementation by intermediaries, but cannot invoke this ‘fair balance’ test against the voluntary removal decisions by the social network service. Drawing on practical examples, this article explores the threat to free speech created by this lack of accountability: Firstly, a shift from legislative regulation and formal injunctions to public-private collaborations allows state authorities to influence these ostensibly voluntary policies, thereby circumventing constitutional safeguards. Secondly, even absent state interference, the commercial incentives of social media cannot be guaranteed to coincide with democratic ideals. In light of the blurring of public and private functions in the regulation of social media expression, this article calls for the increased accountability of the social media services towards end users regarding the observance of free speech principles
