The disappearance of Madeleine McCann: Public drama and trial by media in the Portuguese press

The extraordinary media coverage regarding the disappearance of the British 3-yearold Madeleine McCann emerges as an illustrative example of a ‘public drama’ and ‘trial by media’. This article presents a comparative analysis of the perspectives and narrative devices employed by two Portuguese newspapers in establishing a dialogue with their respective audiences. High-profile mediatized criminal cases have the potential to linger in the public memory and become cultural references which may affect longterm public representations of crime and justice. Our analysis is limited to a sample of representative Portuguese newspapers. We found a basic distinction between ‘quality’ and ‘popular’ press which may be related to inherent differences of their market and implicit audiences. A distanced, neutral and reflexive style of the quality press contrasts with the construction of a sensationalistic narrative by the popular press. The latter provided the audience with a daily dose of vicarious participation in a criminal drama which developed into a trial by media, sustained by a rhetoric that encourages the audience to ‘take sides’. Sensationalist media narratives can potentially undermine the principles of fair trial and the presumption of innocence. But they can also elicit relevant collective energies directed at starting processes of change.Foundation for Science and Technology (Portuguese Ministry of Science, Technology and Higher Education) for financing this research, in the project ‘Justice, media and citizenship’ (PTDC/SDE/67021/2006) hosted at the Centre for Social Studies, University of Coimbrainfo:eu-repo/semantics/publishedVersio

Continuous passive motion applied to whole joints stimulates chondrocyte biosynthesis of PRG4

Continuous passive motion (CPM) is currently a part of patient rehabilitation regimens after a variety of orthopedic surgical procedures. While CPM can enhance the joint healing process, the direct effects of CPM on cartilage metabolism remain unknown. Recent in vivo and in vitro observations suggest that mechanical stimuli can regulate articular cartilage metabolism of proteoglycan 4 (PRG4), a putative lubricating and chondroprotective molecule found in synovial fluid and at the articular cartilage surface. ----- ----- Objectives: (1) Determine the topographical variation in intrinsic cartilage PRG4 secretion. (2) Apply a CPM device to whole joints in bioreactors and assess effects of CPM on PRG4 biosynthesis.----- ----- Methods: A bioreactor was developed to apply CPM to bovine stifle joints in vitro. Effects of 24 h of CPM on PRG4 biosynthesis were determined.----- ----- Results: PRG4 secretion rate varied markedly over the joint surface. Rehabilitative joint motion applied in the form of CPM regulated PRG4 biosynthesis, in a manner dependent on the duty cycle of cartilage sliding against opposing tissues. Specifically, in certain regions of the femoral condyle that were continuously or intermittently sliding against meniscus and tibial cartilage during CPM, chondrocyte PRG4 synthesis was higher with CPM than without.----- ----- Conclusions: Rehabilitative joint motion, applied in the form of CPM, stimulates chondrocyte PRG4 metabolism. The stimulation of PRG4 synthesis is one mechanism by which CPM may benefit cartilage and joint health in post-operative rehabilitation. (C) 2006 Osteoarthritis Research Society International.
