There is little information existing about the spread of lean among Jordanian construction companies. Building on a report by Diekmann et al. (2004), this paper aims to perform a similar investigation among first-grade Jordanian construction companies to assess the extent of implementation of lean techniques.

For this purpose, a quantitative approach to measuring contractors’ conformance to lean practices was adopted. A survey of 61 contractors was conducted using both e-mails and personally delivered surveys that were completed on the spot. The results were analysed, and a practice value index, which indicates the level of implementation, was figured out for lean practices. In addition, an analysis of variance was conducted to determine whether there were differences among respondents from different construction fields.

The survey indicated that some procedures used by Jordanian contractors were consistent with lean construction practices. However, there was no proof that lean concepts were used on a company-wide basis. Furthermore, the survey revealed that the Jordanian construction industry lacks a “continuous improvement“ mentality, suffers from the absence of error proofing devices and provides minimal training at several levels of the organisation.

The outcomes of the study are valuable for contractors and developers of management practices, as it will encourage them to adopt lean construction holistically and identify features that are not exploited in the Jordanian construction industry.

It has often been said that a great part of the strength of Aslib lies in the fact that it brings together those whose experience has been gained in many widely differing fields but who have a common interest in the means by which information may be collected and disseminated to the greatest advantage. Lists of its members have, therefore, a more than ordinary value since they present, in miniature, a cross‐section of institutions and individuals who share this special interest.

Contact problems are among the most difficult ones in mechanics. Due to its practical importance, the problem has been receiving extensive research work over the years. The finite element method has been widely used to solve contact problems with various grades of complexity. Great progress has been made on both theoretical studies and engineering applications. This paper reviews some of the main developments in contact theories and finite element solution techniques for static contact problems. Classical and variational formulations of the problem are first given and then finite element solution techniques are reviewed. Available constraint methods, friction laws and contact searching algorithms are also briefly described. At the end of the paper, a bibliography is included, listing about seven hundred papers which are related to static contact problems and have been published in various journals and conference proceedings from 1976.

Uses Resnik and Stern’s content analysis criteria to examine audio and visual information of in‐cinema slide advertisements within one regional market in Australia to determine whether two types of cues are compatible or reinforce one another. Suggests that there was extensive information framing for a narrow set of information cues. States that there were also significant differences in the types of audio and visual cues, which might result in conflicting information being communicated or information overload.

The reliability of 0·5 mm pitch, 208‐pin FQFP solder joints has been studied by experimental temperature cycling and 3‐D nonlinear finite element analysis. Temperature cycling results have been presented as a Weibull distribution. Thermal fatigue life of the solder joints has been estimated based on the calculated plastic strain and isothermal fatigue data on solders. A correlation between the experimental and analytical results has also been made.

One of the common law duties owed by the employer is his duty to take reasonable care for the safety of his employee. This common law duty is an implied term in the contract of employment and is therefore contractual in nature. Because of the difficulties which may arise in bringing an action in contract for breach of the employer's duty of care, the employee who has sustained injuries during the course of his employment (although he may sue either in contract of tort will normally bring a tort action.

Research suggests effective immersive simulations that rely on augmented reality enhance teachers’ self-efficacy and skills (Badiee & Kauffman, 2015). However, there is a gap in the literature as studies have largely ignored their uses in educational leadership programs (Bradley & Kendall, 2015). This study investigated the relationship between application of critical skills within an immersive simulation environment and 26 school or district leaders’ perceptions of self-efficacy in leading a professional learning community (PLC). Two overarching themes materialized from participants: improved general confidence in leading a PLC, and a sense of refined or expanded skills in the context of new approaches to leading PLC. Further studies are needed on the use of immersive simulation as a pedagogical tool and to examine impact for educational leadership practitioners.

OWING to the comparatively early date in the year of the Library Association Conference, this number of THE LIBRARY WORLD is published so that it may be in the hands of our readers before it begins. The official programme is not in the hands of members at the time we write, but the circumstances are such this year that delay has been inevitable. We have dwelt already on the good fortune we enjoy in going to the beautiful West‐Country Spa. At this time of year it is at its best, and, if the weather is more genial than this weather‐chequered year gives us reason to expect, the Conference should be memorable on that account alone. The Conference has always been the focus of library friendships, and this idea, now that the Association is so large, should be developed. To be a member is to be one of a freemasonry of librarians, pledged to help and forward the work of one another. It is not in the conference rooms alone, where we listen, not always completely awake, to papers not always eloquent or cleverly read, that we gain most, although no one would discount these; it is in the hotels and boarding houses and restaurants, over dinner tables and in the easy chairs of the lounges, that we draw out really useful business information. In short, shop is the subject‐matter of conference conversation, and only misanthropic curmudgeons think otherwise.
