New methods are needed for accessing very large information services. This paper proposes the use of a user model neural network to allow better access to a news service. The network is constructed on the basis of articles read, and articles marked as rejected. It adapts over time to better represent the user's interests and rank the articles supplied by the news service. Using an augmented keyword search we can also search for articles using keywords in conjunction with the user model neural network. Trials of the system in a USENET news environment show promising results for the use of this approach in information retrieval.

Why do significant cultural anomalies frequently fail to generate change in institutional logics? Current process models offer a number of direct ways to enable the creation and diffusion of ideas and practices, but the resistance to adoption and diffusion, something so emphasized by the old institutionalism, has not been incorporated as directly in those models in a way that allows us to answer this question. Therefore, we theorize three retrenchment processes that impede innovation: cultural positioning, behavioral resistance, and feedback shaping. The ways in which these processes work are detailed in a case study of one high profile cultural anomaly: oil production and environmental management in Alberta’s oil sands from 2008 to 2011. Implications for the institutional logics perspective and understanding logics in action are discussed.

The interest for hosting the Olympic Games is now at its historical peak. Heads of states, culture elites, top athletes and professional marketers are engaged in selling their cities to the deciding International Olympic Committee. This host selection process has recently been in the focus of public interest due to the bribery allegations against the winner of the 2002 Olympic Winter Games, Salt Lake City.

Routing in ad hoc networks faces significant challenges due to node mobility and dynamic network topology. In this work we propose the use of mobility prediction to reduce the search space required for route discovery. A method of mobility prediction making use of a sectorized cluster structure is described with the proposal of the Prediction based Location Aided Routing (P‐LAR) protocol. Simulation study and analytical results of P‐LAR find it to offer considerable saving in the amount of routing traffic generated during the route discovery phase.

Purpose – Good investigative sociology and high-quality investigative journalism are not just the same but they are close relatives. For both professions, getting under the surface soil of social life, digging deeply into and making coherent sense of the social experience of others, and translating those findings and interpretations into a universal language for widespread consumption are hugely challenging tasks. Understanding the difference and similarities regarding how sociologists and investigative journalists go about this task raises fundamental philosophical, epistemological, ethical, methodological, theoretical and practical concerns, the outline considerations of which are all featured in this chapter.

Design/methodology/approach – Drawing upon more than three decades of investigative research experience in the field and the original and the innovative personal scholarship that this has yielded, the chapter offers students a map reader's guide of how to navigate a way through the complex, challenging and sometimes hazardous labyrinth of investigative qualitative research.

Originality/value – In addition to offering a ‘how to’ primer for thinking about and doing investigative-qualitative sociology, the chapter also offers advice on how to survive the experience and authoritatively tell the tale well to the widest possible audiences.

THE author of this little sketch is happy to bear witness of the endurance and strength of a Scottish editor; a fifth of a century ago the projector of the LIBRARY REVIEW, who has remained at its heim ever since, asked for an article for the first number of his journal. That paper came from the West Coast, that is California, and tried to disclose some library items of a hopeful nature. Since that year the world has for a time gone mad, but the REVIEW has continued to promote libraries, reading and books.
