Richard Cox responds to the attacks by Nicolson Baker against the library community. Deals with each of Baker’s main points: that a lie was foisted on the public about the care of newspapers, the insidious destruction of original newspapers, the resultant loss of trust by the public in libraries and archives and a set of wrong priorities leading to the misguided microfilming and destruction of newspapers.

This study examines the discursive accounts of civil society in a rural English village to understand what these reveal about contemporary political discourses. It employs a critical discourse analysis of the conversational interactions of Ambridge residents. The sample comprised all recorded conversations referencing charities, volunteering and civic action drawn from the two-week period corresponding with the change in UK Prime Minister (July 2019). Using three analytical tools derived from extant theory, it considers the salient political ideology underpinning these social interactions. These tools are illustrated with earlier examples of individual civil activities such as the oat-based civil disobedience of a respected older resident. This analysis scrutinises the philanthropic nature of Peggy Woolley's Ambridge Conservation Trust. The fraught process of village fete planning is cited as exemplifying conventional decision-making mechanisms. Problems of staffing a community shop are considered in the light of an increasing political reliance on community volunteers replacing paid staff. Thus, the relative impact of Thatcher, Blair, Cameron and May are considered in exchanges between Ambridge residents from Lynda and Robert Snell to Jazzer McCreery and Jill Archer. The aim is to explore what Ambridge's civil society tells us about Boris Johnson's Britain.

This study aims to find a feasible precise navigation model for the planed Lunar rover. Autonomous navigation is one of the most important missions in the Chinese Lunar exploration project. Machine vision is expected to be a promising option for this mission because of the dramatic development of an image processing technique. However, existing attempts are often subject to low accuracy and errors accumulation.

In this paper, a novel autonomous navigation model was developed, based on the rigid geometric and photogrammetric theory, including stereo perception, relative positioning and absolute adjustment. The first step was planned to detect accurate three-dimensional (3D) surroundings around the rover by matching stereo-paired images; the second was used to decide the local location and orientation changes of the rover by matching adjacent images; and the third was adopted to find the rover’s location in the whole scene by matching ground image with satellite image. Among them, the SURF algorithm that had been commonly believed as the best algorithm for matching images was adopted to find matched images.

Experiments indicated that the accurate 3D scene, relative positioning and absolute adjustment were easily generated and illustrated with the matching results. More importantly, the proposed algorithm is able to match images with great differences in illumination, scale and observation angle. All experiments and findings in this study proved that the proposed method could be an alternative navigation model for the planed Lunar rover.

With the matching results, an accurate 3D scene, relative positioning and absolute adjustment of rover can be easily generated. The whole test proves that the proposed method could be a feasible navigation model for the planed Lunar rover.
