Abstract
Purpose
This study aims to explore the impact of multisource deformation errors on the oil film contact surface, which arise from manufacturing, assembly, oil pressure and thermal influences, on the motion accuracy of hydrostatic guideway.
Design/methodology/approach
Using thermal-structural coupling simulations, this research investigates the effects of assembly, oil pressure and thermal factors on deformation errors of the oil film contact surface. By integrating these with manufacturing errors, a profile error model for the oil film contact surface is developed, characterizing the cumulative effect of these errors. Using kinematic theory and progressive Mengen flow controller characteristics, the motion error at any position of the hydrostatic guideway is quantified, examining how surface error traits impact motion accuracy.
Findings
The error averaging effect is affected by the profile error of oil film contact surface. Meanwhile, the motion accuracy of hydrostatic guideway is highly sensitive to the oil film contact surface error amplitude.
Originality/value
This approach allows for precise prediction and analysis of motion accuracy in hydrostatic guideways during the design and manufacturing stages. It also provides guidance for planning process tolerances.

Abstract
The librarian and researcher have to be able to uncover specific articles in their areas of interest. This Bibliography is designed to help. Volume IV, like Volume III, contains features to help the reader to retrieve relevant literature from MCB University Press' considerable output. Each entry within has been indexed according to author(s) and the Fifth Edition of the SCIMP/SCAMP Thesaurus. The latter thus provides a full subject index to facilitate rapid retrieval. Each article or book is assigned its own unique number and this is used in both the subject and author index. This Volume indexes 29 journals indicating the depth, coverage and expansion of MCB's portfolio.

Abstract
Since the first Volume of this Bibliography there has been an explosion of literature in all the main areas of business. The researcher and librarian have to be able to uncover specific articles devoted to certain topics. This Bibliography is designed to help. Volume III, in addition to the annotated list of articles as the two previous volumes, contains further features to help the reader. Each entry within has been indexed according to the Fifth Edition of the SCIMP/SCAMP Thesaurus and thus provides a full subject index to facilitate rapid information retrieval. Each article has its own unique number and this is used in both the subject and author index. The first Volume of the Bibliography covered seven journals published by MCB University Press. This Volume now indexes 25 journals, indicating the greater depth, coverage and expansion of the subject areas concerned.

Abstract
The size of the population classified as people with disabilities or older adults is increasing globally. The World Health Organization estimates that the average prevalence of disability is around 18% among adults age 18 and older. People with disabilities and older adults have lower levels of physical activity and experience significant barriers to walking in local neighbourhoods. A new perspective is needed that views disability in the context of the built environment and across the lifespan. The purpose of this chapter is to examine walking as an activity that is inclusive of any age, ability or assistive device used for mobility. Through a literature review, we illustrate the complex relationship that exists between individuals with disabilities/older adults and the built environment. We describe environmental and social factors, which have been found to be associated with walking among people with disabilities and older adults as well as factors perceived to be barriers to walking. Factors cited in the literature include aspects that fall into the environmental domains of the International Classification of Functioning. We conclude by highlighting key factors needed for planning supportive walking environments for people with disabilities and older adults. Recommendations include the use of walking audits to gain information on detailed aspects of the built environment, developing inclusive walking initiatives, including people with disabilities and older adults in the planning process and planning for maintenance.

Abstract
Chapter Summary
This chapter focuses on accelerating the adoption and promotion of the solution across the organization. The authors define acceleration as achieving the maximum effective and appropriate use of the solution across the organization. This capability is strategic – it ensures that any new intelligence solution or activity is part of its business product line. The initial focus is on internal business products, but organizations are also encouraged to see new solutions as potential external products. To ensure the product is strategically leveraged, business managers, designers, and analysts must work with leaders to socialize solutions and encourage their adoption. It also means being open to adapting and calibrating the solution over time. This chapter also includes practical business stories.
