Open access combined with Web 2.0 networking tools is fast changing the traditional journal's functions and framework and the publisher's role. As content is more and more available online in digital repositories and on the web, an integrated, interconnected, multidisciplinary information environment is evolving and Oldenburg's model disintegrates: the journal is no longer the main referring unit for scholarly output, as it used to be, for Scientific, Technical, and Medical disciplines, but scholars' attention is now more focused on the article level. New journals models are thus evolving. The first part of this paper discusses these new experimental journal models, i.e. overlay journals, interjournals and different levels journals. The second part directs readers' attention to the role commercial publishers could play in this digital seamless writing arena. The authors consider that publishers should concentrate much more on value-added services for authors, readers and libraries, such as navigational services, discovery services, archiving and evaluation services.

Within rehabilitation, there is a great need for a simple method to monitor wheelchair use, especially whether it is active or passive. For this purpose, an existing measurement technique was extended with a method for detecting self- or attendant-pushed wheelchair propulsion. The aim of this study was to validate this new detection method by comparison with manual annotation of wheelchair use. Twenty-four amputation and stroke patients completed a semi-structured course of active and passive wheelchair use. Based on a machine learning approach, a method was developed that detected the type of movement. The machine learning method was trained based on the data of a single-wheel sensor as well as a setup using an additional sensor on the frame. The method showed high accuracy (F1 = 0.886, frame and wheel sensor) even if only a single wheel sensor was used (F1 = 0.827). The developed and validated measurement method is ideally suited to easily determine wheelchair use and the corresponding activity level of patients in rehabilitation.
