The National Transport Data Framework

Report by Professor Peter Landshoff (Cambridge University) and Professor John Polak (Imperial College London) on a project for the Department for Transport. emails: [email protected] [email protected] NTDF is designed to be a resource for data owners to deposit descriptions into a central catalogue, so that people can search for data and find data and understand their characteristics. The value of this is to individuals, to commercial organizations, and to public bodies. For example, services that provide better information to travellers will help to make their journey less stressful and persuade them to make more use of public transport. Transport operators need very diverse information to help them plan developments to their services: demographic, geographical, economic etc. And policy makers need a similar range of information to help them decide how to divide their budget and afterwards to evaluate how valuable it has been.This work was supported by the Department for Transport (DfT)

These days, shipbuilding companies are making an effort to adopt the IT technology in order to improve the production efficiency. One such effort is to utilize a planning and scheduling system to predict the production cost in advance. In this system, assessing the welding material quantity is an important factor. Unfortunately, obtaining the welding material quantity in the early design stage is extremely difficult because the detailed production information, which is essential in deriving the cost associated with welding, is normally available at a later stage. This paper aims at developing a computerized program that produces an index to estimate the welding material quantity in the early design stage. By using only three-dimensional geometric information, the program analyzes the production process and estimates the welding material quantity at any design or production stage when no production information is available. The results can be used for the planning and scheduling system.1. Introduction 2.

Access barriers : an investigation into the availability and accessibility of high-demand materials in the Short Loan Centre of an academic library

Bibliography: p. 175-197.Academic libraries in South Africa are facing the challenge of tighter budgets, increasing student enrolments, greater diversity in students' backgrounds and library experience, and a call for greater accountability to all the stakeholders. The effectiveness of a library service can be measured in terms of the availability and accessibility of library materials, two attributes of a library's document delivery capability. This study focused on the availability of prescribed materials for undergraduate students in an academic library. It involved a micro-evaluation of the immediate materials availability rate in a short loan collection, by using a combination of a quantitative simulation study, and a qualitative user survey. Generally, the availability rates determined were high, which suggests a high degree of collection adequacy. However, the user study confirmed that many SLC users experienced difficulties in using the system, indicating a need for continuous user education programmes and constant dialogue between the staff and the users concerning future service improvements. The study indicated that overall materials availability rates can be misleading if accepted at face value. A introspective analysis of the reasons for the non-availability of high-demand materials revealed hidden access barriers such as poor information retrieval skills on the part of the users and certain inefficient organisational procedures on the part of the library. The study reiterates the fundamental importance of constructive communication between the various stakeholders in meeting the educational goals of the institution and the necessity of regular library performance evaluation to ensure a dynamic, proactive service. The coexistence of print-based and electronic resources in the forseeable future underscores the importance of convenience and accessibility factors in making required documents available to the users
