Context Aware e-Learning Objects and their Types from the Perspective of the Object-Oriented Paradigm

The contribution of this article demonstrates how to identify context-aware types of e-Learning objects (eLOs) derived from the subject domains. This perspective is taken from an engineering point of view and is applied during requirements elicitation and analysis relating to present work in constructing an object-oriented (OO), dynamic, and adaptive model to build and deliver packaged e-Learning courses. Consequently, three preliminary subject domains are presented and, as a result, three primitive types of eLOs are posited. These types educed from the subject domains are of structural, conceptual, and granular nature. Structural objects are responsible for the course itself, conceptual objects incorporate adaptive and logical interoperability, while granular objects congregate granular assets. Their differences, interrelationships, and responsibilities are discussed. A major design challenge relates to adaptive behaviour. Future research addresses refinement on the subject domains and adaptive hypermedia systems.

Object-Based Customization of Learning Content: Potentials and Pitfalls

Specification consortia and standardization bodies concentrate on e-Learning objects to en-sure reusability of content. Learning objects may be collected in a library and used for deriv-ing course offerings that are customized to the needs of different learning communities. How-ever, customization of courses is possible only if the logical dependencies between the learn-ing objects are known. Metadata for describing object relationships have been proposed in several e-Learning specifications. This paper discusses the customization potential of e-Learning objects but also the pitfalls that exist if content is customized inappropriately.

Literary Encounters of Fundamentalism: A Case Book

Literature, literary interpretation and criticism have always had an interestingly paradoxical relationship with fundamentalism: fundamentalisms are generally built on texts, which can be sacred and exclusive, and on a claim to exclusive authority for interpretation. Therefore they tend to see the cornucopian profusion of texts and interpretations so typical of Western concepts of Literature as a threat; a circumstance which has been widely exploited by writers and critics to engage with fundamentalism on its home turf. The volume addresses the cultural given that the term ‘fundamentalism’ has acquired such wide-spread currency, at least in the West. In their various approaches, the contributions examine what fundamentalism has come to signify for those who use the term so extensively and so indiscriminately; and they try to establish what this implies for reaching more productive and positive positions in negotiating fundamentalisms. In doing so, the contributors offer investigations of literary approaches to fundamentalism across a wide range of important contemporary discourses and from a number of cultural perspectives. Readers will expand their understanding of the significance of fundamentalism, and of the value of literature as a highly specialized medium for explorations in this field.

Detecting single-target changes in multiple object tracking: The case of peripheral vision

In the current study it is investigated whether peripheral vision can be used to monitor multi-ple moving objects and to detect single-target changes. For this purpose, in Experiment 1, a modified MOT setup with a large projection and a constant-position centroid phase had to be checked first. Classical findings regarding the use of a virtual centroid to track multiple ob-jects and the dependency of tracking accuracy on target speed could be successfully replicat-ed. Thereafter, the main experimental variations regarding the manipulation of to-be-detected target changes could be introduced in Experiment 2. In addition to a button press used for the detection task, gaze behavior was assessed using an integrated eye-tracking system. The anal-ysis of saccadic reaction times in relation to the motor response shows that peripheral vision is naturally used to detect motion and form changes in MOT because the saccade to the target occurred after target-change offset. Furthermore, for changes of comparable task difficulties, motion changes are detected better by peripheral vision than form changes. Findings indicate that capabilities of the visual system (e.g., visual acuity) affect change detection rates and that covert-attention processes may be affected by vision-related aspects like spatial uncertainty. Moreover, it is argued that a centroid-MOT strategy might reduce the amount of saccade-related costs and that eye-tracking seems to be generally valuable to test predictions derived from theories on MOT. Finally, implications for testing covert attention in applied settings are proposed.

Towards a Literary Hermeneutics of the Borders and the Borderlands

Si les frontières constituent un thème majeur dans nombre d’œuvres littéraires, encore faut-il se demander d’une part comment les définir (ce qui nécessite d’en dresser une typologie), d’autre part comment elles sont figurées littérairement. Cet article théorique est un préambule à un travail herméneutique qui pourra porter sur des œuvres très diverses où sont figurées des frontières.
