Interactive Model (interactive + model)
Selected AbstractsA multiple-theory analysis of a diffusion of information technology caseINFORMATION SYSTEMS JOURNAL, Issue 3 2001Richard Baskerville Abstract. This paper describes a multiple-theory analysis of a diffusion of information technology case. Three innovation diffusion models, the interactive model, the linked-chain model and the emergent model, are used to develop an analysis that describes the essential knowledge that each model produces. Rather than develop conflicting stories, each model leads to distinctly different, but complementary, knowledge about the case setting. More generally, the analysis enables us to circumscribe the distinct conceptual domain of each model. These domains define the scope of research questions that can be addressed by each of the innovation diffusion models. In addition to the theoretical implications, the paper also describes the practical indications and actions of the case subjects. [source] An interactive process model of psychosocial support needs for women living with breast cancer,PSYCHO-ONCOLOGY, Issue 4 2003Beth Marlow Psychosocial support is acknowledged as an important aspect of the care and recovery process for women diagnosed with breast cancer. To develop an understanding of support needs, a series of focus groups were conducted with a total of 80 Australian women living with breast cancer. The psychosocial needs identified in discussion were summarised into four main categories, Organisation of Care, Sense of Control, Validation of Experience and Feeling of Reassurance. From these themes an interactive model of psychosocial support needs was developed. As a process model it demonstrates that the provision of effective support is, necessarily, an integrated, not a piecemeal, process. The categories of support are broad, and are made more inclusive through interactions with each other, providing room to accommodate individual needs and styles of adjustment. The model is not esoteric or complicated , it is an accessible overview of the process for both client and helper. Copyright © 2003 John Wiley & Sons, Ltd.

The brachial plexus was finely dissected and injected with contrast medium and leaden markers were implanted into the nerves at predefined places. A reverse shoulder prosthesis was inserted in a cadaveric specimen what induced positional change in the upper limb nerves. Computed tomography (CT) was performed before and after this surgical intervention. The computer assisted image processing package Mimics® was used to reconstruct the pre- and postoperative brachial plexus in 3D. The results show that the current interactive model is a realistic and detailed representation of the specimen used, which allows 3D study of the brachial plexus in different configurations. The model estimated strains up to 15.3% and 19.3% for the lateral and the medial root of the median nerve as a consequence of placing a reverse shoulder prosthesis. Furthermore, the model succeeded in calculating the displacement of the brachial plexus by tracking each implanted lead marker. The presented brachial plexus 3D model currently can be used in vitro for cadaver biomechanical analyses of nerve movement to improve diagnosis and treatment of peripheral neuropathies. The model can also be applied to study the exact location of the plexus in unusual upper limb positions like during axillary radiation therapy and it is a potential tool to optimize the approaches of brachial plexus anesthetic blocks.

[source] Making War on Terror?THE MODERN LAW REVIEW, Issue 6 2006Global Lessons from Northern Ireland In place of the simple modelling employed in anti-terrorist legal discourse, this article posits an interactive model of the relationship between the state and violent political actors, exploring law's role in both the repression and mobilisation of challengers. Drawing on social movement theory, it hypothesises a process of ,legally implicated mobilisation' which takes account both of law's presence and its partial absence in ,legal grey zones' during violent conflict, and it suggests how law may impact upon key elements of the mobilisation process. The hypothesis is applied to qualitative data from Northern Ireland on violent challengers. The data point to the importance of ,messaging' about law in the state of exception, supporting claims that law can have a ,damping' effect on violent conflict. The relationship between repression and violence is partly symbiotic, and in the global ,war on terror,' prisoner-abuse may have a mobilising effect on violent challengers. [source] Family Risk of Dyslexia Is Continuous: Individual Differences in the Precursors of Reading SkillCHILD DEVELOPMENT, Issue 2 2003Margaret J. Snowling The development of 56 children at family risk of dyslexia was followed from the age of 3 years, 9 months to 8 years. In the high-risk group, 66% had reading disabilities at age 8 years compared with 13% in a control group from similar, middle-class backgrounds. However, the family risk of dyslexia was continuous, and high-risk children who did not fulfil criteria for reading impairment at 8 years performed as poorly at age 6 as did high-risk impaired children on tests of grapheme,phoneme knowledge. The findings are interpreted within an interactive model of reading development in which problems in establishing a phonological pathway in dyslexic families may be compensated early by children who have strong language skills. [source] A rhythm recognition computer program to advocate interactivist perceptionCOGNITIVE SCIENCE - A MULTIDISCIPLINARY JOURNAL, Issue 1 2004Jean-Christophe Buisson Abstract This paper advocates the main ideas of the interactive model of representation of Mark Bickhard and the assimilation/accommodation framework of Jean Piaget, through a rhythm recognition demonstration program. Although completely unsupervised, the program progressively learns to recognize more and more complex rhythms struck on the user's keyboard. It does so without any recording of the input flow, and without any pattern matching in the usual sense. On the contrary, internal processes are dynamically constructed to follow and anticipate the user's actions. We show that these processes are representations of the rhythms in the interactivist sense, and that they emerge from non representational grounds, avoiding the symbol-grounding problem. They are not copies or transductions of reality, but ideal internal constructions of the agent, avoiding the circularity pointed out by Piaget. In practice, the active nature of this recognition process allows it to work even with noisy and complex input flows. [source] | ||||||||||
