ENGINE lubricating oil filtration is not an exact science. Despite recent advances, detailed understanding of how filters and filtration systems operate is sparse, yet filters are known to facilitate dramatic reductions in engine wear. This paper relates the size of contaminants found in used oil to the magnitudes of the oil films between the lubricated components, in order to define the required filtration level in engines. The results of wear tests with oil contaminated by small particles are used to confirm the filtration requirement.

Discusses research carried out by the Advanced Manufacturing and Automation Research Centre [AMARC], University of Bristol into the automation of two areas of meat production, the butchery of half carcasses into main joints and the evisceration of whole carcasses. Describes how the robotic butchery process requires sensing, determination of cut‐paths and trajectories for the robot, mechanical cutting using appropriate tools and the ability to transport, manipulate and hold each carcass during cutting and how each of these areas bas been integrated into a practical system. Also describes the system developed for robotic evisceration. Concludes that this research work has led to two industrial demonstrator systems for processing meat carcasses which have had encouraging response from potential customers.

Entrepreneurial coaching appears to be a sufficiently customized way to help novice owner‐managers develop their managerial skills. However, its usefulness remains to be verified. The purpose of this research is thus to examine the effectiveness of coaching as a support measure for young entrepreneurs and to identify the factors likely to have an impact on the success of coaching initiatives.
Given the exploratory nature of the study, a flexible and open approach was chosen in order to explore the concept of coaching in some depth. The strategy retained was the case study method, with inter‐site comparisons of six coaching initiatives.
The findings suggest that the success of a coaching relationship is explained by a set of factors or “winning conditions”, some of which are more important than others. The most crucial one appears to be the entrepreneur's open attitude to change.
The main limitation of this study is the small number of cases observed.
This research provides valuable information on coaching initiatives by means of real‐life examples. It also highlights several factors likely to improve the delivery of coaching services to novice entrepreneurs. It will thus prove useful to those designing coaching programs for entrepreneurs.
Given the lack of documentation on the subject of entrepreneurial coaching, this paper has the merit of identifying some of the elements likely to contribute to the success of coaching initiatives. In addition, its findings will fuel thinking on how to enhance the benefits of coaching for novice entrepreneurs.

We report the findings from a study exploring the experiences of individuals undergoing MRI scanning for research. Semi‐structured interviews took place before and after scanning with 17 participants; 12 were healthy volunteers and five were patients with a diagnosis of remitted depression. Themes of apprehension and curiosity prior to scanning were common in both groups. Patients were often confused about the procedure. Negative feelings were an issue at the outset, characterised by shock related to the physical surroundings, after which positive feelings, for example relaxation, were often experienced, and in the case of patients, learning more about their brain. Written information about imaging was deemed satisfactory; however the ability to ‘experience’ aspects of scanning beforehand was suggested. Scanning may be viewed as a process beginning prior to the procedure itself and involving positive and negative emotions. Increased information, reassurance and a more interactive intervention to reduce anxiety may be beneficial and may improve individuals' experience of this widely used procedure.

Allegations of excessive force in policing have been cited as one of the most frequent claims filed against the police in arrest situations. The United States Supreme Court in Graham v. Connor (1989) determined that “objective reasonableness” is the Fourth Amendment standard to be used in evaluating claims of excessive force. This paper analyzes the patterns of lower federal court decisions in 1,200 published Section 1983 cases decided from 1989 to 1999. The assessment examines how these courts have applied and interpreted the standard in four categories involving force. Policy and training issues are discussed and future research concerns are presented.

Our examination of accounting and violence aims to reinvigorate what it means to provide accountability and visibility given that knowledge and values are socially constructed. The authors follow the legacy of critical accounting research in this essay, using counter accounts, shadow accounting, and narratives to uncover the discipline’s relationship to violence, women, and migrants.
