The turning point in 1985. The history of appraisal and disposal of records in Iceland

The article sets off with a brief summary of the history of appraisal and disposal of records as processed at the National Archives of Iceland (NAI) since its establishment in 1882 to present times. Rules on appraisal and disposal of records introduced in 1900, 1911, and 1916 were ignored and all records were kept. Status quo remained until 1985 when a new National Archives Act was passed. The appraisal and disposal process adopted then is described and explained. It included the publication of instructions on records management as well as forms relating to records management. The influence of acts of law on the appraisal and disposal process is explained. Finally the experience with the arrangement of organised appraisal in Iceland is described.     

Neuropsychological classification and treatment of dyslexia.

Evidence shows that initial and advanced learning to read are predominantly mediated by the right and left cerebral hemispheres, respectively. Premature reliance on left-hemispheric reading strategies may result in L-type dyslexia, characterized by hurried and inaccurate reading. P-type dyslexia, characterized by a slow and fragmented style of reading, may result from the inability to shift from the predominant generation of right-hemispheric reading strategies to the predominant generation of left-hemispheric reading strategies. Results of investigations concerning the validity of the L/P-typology are discussed, as are the reading effects of hemisphere-specific and hemisphere-alluding stimulation in children with L- and P-type dyslexia.     

Ensuring Content‐Area Learning by Secondary Students with Learning Disabilities

Three factors tied with secondary student success in content‐area reading are demonstrated: (a) validated teacher‐focused and student‐focused interventions, (b) integrated and comprehensive service delivery systems, and (c) well‐designed, data‐based professional developmental programs. Difficult challenges face secondary students with LD and their teachers with regard to these students’ participation and success in required general education classes. Recently, instructional methods and materials have been developed and validated for promoting these students’ success. Some of them focus on how general education teachers plan and teach their content‐area courses; others focus on giving students the strategies they need to respond independently to the demands of their courses. This article describes these instructional methods, a service‐delivery model for implementing these interventions in secondary schools, and professional‐development mechanisms and administrative support that must be in place for the model to be maintained effectively.     

Toward a Programmatic Pragmatism: A Response to Naoko Saito

Naoko Saito has made a good case for emphasising the 'tragic' dimension within Dewey's pragmatism. My response suggests ways in which Saito has not gone far enough. She does not adequately move beyond 'procedural pragmatism' to a 'programmatic pragmatism' which offers substantive articulations about the human good. In addition, her emphasis on 'Emersonian perfectionism' is misguided. Both the language of 'perfectionism' and the figure of Emerson are unsuitable for the project she intends. Speaking more concretely of a 'tragic–comic meliorism' allied to the novelist Hawthorne, it is suggested, provides a more fruitful path.
