This briefing paper offers insight into various open access business models, from institutional to subject repositories, from open access journals to research data and monographs. This overview shows that there is a considerable variety in business models within a common framework of public funding. Open access through institutional repositories requires funding from particular institutions to set up and maintain a repository, while subject repositories often require contributions from a number of institutions or funding agencies to maintain a subject repository hosted at one institution. Open access through publication in open access journals generally requires a mix of funding sources to meet the cost of publishing. Public or charitable research funding bodies may contribute part of the cost of publishing in an open access journal but institutions also meet part of the cost, particularly when the author does not have a research grant from a research funding body

Traditional software development captures the user needs during the requirement analysis. The Web makes this endeavour even harder due to the difficulty to determine who these users are. In an attempt to tackle the heterogeneity of the user base, Web Personalization techniques are proposed to guide the users’ experience. In addition, Open Innovation allows organisations to look beyond their internal resources to develop new products or improve existing processes. This thesis sits in between by introducing Open Personalization as a means to incorporate actors other than webmasters in the personalization of web applications. The aim is to provide the technological basis that builds up a trusty environment for webmasters and companion actors to collaborate, i.e. "an architecture of participation". Such architecture very much depends on these actors’ profile. This work tackles three profiles (i.e. software partners, hobby programmers and end users), and proposes three "architectures of participation" tuned for each profile. Each architecture rests on different technologies: a .NET annotation library based on Inversion of Control for software partners, a Modding Interface in JavaScript for hobby programmers, and finally, a domain specific language for end-users. Proof-of-concept implementations are available for the three cases while a quantitative evaluation is conducted for the domain specific language.

The development of an openly available layer of scholarly and scientific content requires access to all types of output from the scholarly and scientific process. Interoperable and sustainable infrastructure components are invaluable elements and the content should be clearly licensed for re-use. Open Knowledge will improve the discoverability and re-usability of content across the sectors, to the benefit of higher education and research and will help the (European) knowledge economy to move forward. In Autumn 2013, scoping sessions took place with experts to discuss their views around the value of making knowledge open and the steps which need to be taken to achieve this. These discussions are collected in the Knowledge Exchange discussion paper on Open Knowledge.

Briefing Note for Jisc – Cameron Neylon – March 2016

The report on the ‘Pathways to Open Scholarship’ conference, organised by Knowledge Exchange to celebrate its 10th anniversary, contains an overview of the views that invited speakers and experts in the audience expressed on Open Scholarship developments. Open Scholarship is not yet a reality of everyday research and education. The event reported on, addressed the concept of "open scholarship" by debating issues and key challenges with the aim to identify pathways forward. Four central themes which represent crucial dimensions of open scholarship have been explored: Benefits, risks and limitations of Open Scholarship; Success as a researcher; Technology; and Publishing and publication services. The report contains views, expectations, wishes and frustrations that experts have on open scholarship, as well as new and promising initiatives and approaches. The report is a starting point for future planning of KE activity and input for a range of consultation talks with respected experts and leaders in the research community in KE countries and beyond.

The JTZ model [C. Jung, T. T¶el and E. Ziemniak, Chaos 3, (1993) 555], as a theoretical model of a plane wake behind a circular cylinder in a narrow channel at a moderate Reynolds number, has previously been employed to analyze phenomena of chaotic scattering. It is ex- tended here to describe an open plane wake without the con¯ned nar- row channel by incorporating a double row of shedding vortices into the intermediate and far wake. The extended JTZ model is found in qualitative agreement with both direct numerical simulations and ex- perimental results in describing streamlines and vorticity contours. To further validate its applications to particle transport processes, the in- teraction between small spherical particles and vortices in an extended JTZ model °ow is studied. It is shown that the particle size has signif- icant in°uences on the features of particle trajectories, which have two characteristic patterns: one is rotating around the vortex centers and the other accumulating in the exterior of vortices. Numerical results based on the extended JTZ model are found in qualitative agreement with experimental ones in the normal range of particle sizes.
