'Balance of Terror' -- Rival Militias and Vigilantes in Nigeria

Militias and vigilantes that assume public authority by fighting crime reject the laws of the state, yet they have no other set of rules to regulate their activities. Many of them claim to be accountable to their ethnic or religious community on whose behalf they operate. But their communities have found no means to institutionalise control over them. Moreover, there are no institutions to settle conflicts between different militias and vigilantes. On a local level, rival groups have reached informal arrangements. However, these compromises are unstable, as they reflect fragile alliances and shifting balances of power. Leaders of militias and other 'self-determination groups' have suggested organising a conference of all ethnic nationalities in Nigeria in order to design a new constitution that would give militias and vigilantes a legal role and define their authority. But the groups compared in this article – Oodua People's Congress, Sharia Vigilantes, Bakassi Boys, MASSOB, and Niger Delta militias – pursue very divergent interests, and they are far from reaching a consensus on how to contain violence between them.

Christina Higgins. 2009. English as a Local Language

Christina Higgins credibly presents the situation of English in East Africa as scrutinized from four areas, which she investigated in the field: the newspaper journalism, annual beauty pageants for young women, the hip hop music of the youth, and advertisements. For me, as a Tanzanian, it has been a pleasure to review a book that illuminatingly documents the language situation, the cultural conceptualization and the localization of English that is taking place in the multilingual society in Tanzania.

Learning through life

Web 2.0 und soziale Netzwerke gaben erste Impulse für neue Formen der Online-Lehre, welche die umfassende Vernetzung von Objekten und Nutzern im Internet nachhaltig einsetzen. Die Vielfältigkeit der unterschiedlichen Systeme erschwert aber deren ganzheitliche Nutzung in einem umfassenden Lernszenario, das den Anforderungen der modernen Informationsgesellschaft genügt. In diesem Beitrag wird eine auf dem Konnektivismus basierende Plattform für die Online-Lehre namens “Wiki-Learnia” präsentiert, welche alle wesentlichen Abschnitte des lebenslangen Lernens abbildet. Unter Einsatz zeitgemäßer Technologien werden nicht nur Nutzer untereinander verbunden, sondern auch Nutzer mit dedizierten Inhalten sowie ggf. zugehörigen Autoren und/oder Tutoren verknüpft. Für ersteres werden verschiedene Kommunikations-Werkzeuge des Web 2.0 (soziale Netzwerke, Chats, Foren etc.) eingesetzt. Letzteres fußt auf dem sogenannten “Learning-Hub”-Ansatz, welcher mit Hilfe von Web-3.0-Mechanismen insbesondere durch eine semantische Metasuchmaschine instrumentiert wird. Zum Aufzeigen der praktischen Relevanz des Ansatzes wird das mediengestützte Juniorstudium der Universität Rostock vorgestellt, ein Projekt, das Schüler der Abiturstufe aufs Studium vorbereitet. Anhand der speziellen Anforderungen dieses Vorhabens werden der enorme Funktionsumfang und die große Flexibilität von Wiki-Learnia demonstriert.

Learning in Virtual Worlds: Research and Applications

Three-dimensional (3D) immersive virtual worlds have been touted as being capable of facilitating highly interactive, engaging, multimodal learning experiences. Much of the evidence gathered to support these claims has been anecdotal but the potential that these environments hold to solve traditional problems in online and technology-mediated education—primarily learner isolation and student disengagement—has resulted in considerable investments in virtual world platforms like Second Life, OpenSimulator, and Open Wonderland by both professors and institutions. To justify this ongoing and sustained investment, institutions and proponents of simulated learning environments must assemble a robust body of evidence that illustrates the most effective use of this powerful learning tool. In this authoritative collection, a team of international experts outline the emerging trends and developments in the use of 3D virtual worlds for teaching and learning. They explore aspects of learner interaction with virtual worlds, such as user wayfinding in Second Life, communication modes and perceived presence, and accessibility issues for elderly or disabled learners. They also examine advanced technologies that hold potential for the enhancement of learner immersion and discuss best practices in the design and implementation of virtual world-based learning interventions and tasks. By evaluating and documenting different methods, approaches, and strategies, the contributors to Learning in Virtual Worlds offer important information and insight to both scholars and practitioners in the field.
