Hal Hendrick was a true International Ergonomist, indeed probably the most universally acknowledged Ergonomist; and although he was always interested in, and committed to ergonomics development around the globe, he had a special empathy with our situation in South Africa. It is therefore a great honour to dedicate this issue of "Ergonomics SA" to Hal Hendrick, a man who devoted his life to the spread of ergonomics to the far corners of the earth.

Over the years Ergonomics SA has striven to be an internationally recognised journal which publishes research conducted in developing countries around the globe. With the current support from the IEA, and the holding of the ODAM Conference in Grahamstown, South Africa earlier this year, we, as Industrially Developing Countries (IDCs), have had extensive exposure for the growing number of outstanding ergonomics projects being run within IDCs. It is therefore imperative that the problems, solutions, ideas, and developments in the various regions be shared with others in order that we become more aware of what is being done in a cross section of IDCs and are able to draw on this knowledge to assist in improving our own local conditions. We therefore urge all IDCs to publish their work in recognized journals such as Ergonomics SA. While papers based on rigorous laboratory research are the backbone of any academic journal, in developing countries there is a crucial need for articles discussing tried and tested practical applications. Hence papers on field-work, both in the form of empirical studies and as assessments of the benefits of practical implementations within industry, are sorely sought for publication. This journal offers Ergonomists in IDCs the opportunity to present work done in developing countries, allowing other developing regions to benefit from their findings.
Opinion section : shaping the future ergonomics landscape of South Africa : a co-operative co-responsibilityAuthor Andrew I. ToddSource: Ergonomics SA : Journal of the Ergonomics Society of South Africa 23, pp 5 –8 (2011)More Less
The Ergonomics Society of South Africa (ESSA) was inaugurated in 1985 and became a federated society of the International Ergonomics Association in 1994 (James and Scott, 2009). Since its inception there have been many significant changes in South Africa, not least of all is a drop in the average life expectancy from well in the 60s during the 1980s to around 54 in 2010 (World Health Organization 2011). Two key roles of ESSA are to promote an awareness of ergonomics and to facilitate discussions on how best to ensure the future success of the discipline within the South African Context. It is therefore necessary from time to time to take stock of where a society is going in order to ensure the aforementioned goals are being achieved. After, together with Rhodes University, having successfully hosted the Human Factors in Organizational Design and Management conference in Grahamstown in the April of 2011, now is a good time to facilitate such discussions within the South African Ergonomics community.
An introductory overview of the 20th International Symposium on Shift work and Working time : research opportunities for South AfricaAuthor Jonathan DavySource: Ergonomics SA : Journal of the Ergonomics Society of South Africa 23, pp 9 –19 (2011)More Less
Irregular work schedules and work performed at night has been associated with a number of health and work-related challenges, which originate from the circadian, sleep and lifestyle-related disruptions inherent in such work arrangements. Work hours, in general, have a significant impact on the way people live their lives and as such, understanding "the how and the why" is crucial in order to limit any possible negative developments. An international meeting on shift work was held in Stockholm, Sweden between the 28th of June and the 1st of July this year, hosted by the Stress Research Institute. This biennial event began in 1969, with the first meeting being held in Oslo, Norway, at which there were no more than 30 participants. In 2011, by comparison, over 240 researchers from 30 different countries attended this 20th meeting of the Working Time Society. Such gatherings have served as the platform for researchers and practitioners from around the world to share their experiences and findings related to working time arrangements, and this meeting was no exception. In the opening address, the Chair of the conference organising committee, Professor Kecklund highlighted that throughout the world, work time arrangements show significant variety and stages of development, which in itself presents numerous challenges when it comes to researching, understanding and managing the impacts of such schedules in different contexts. This is why such international meetings are vital.
Leadership and work pressure as predictors of health and safety (H&S) behaviour in the South African construction industrySource: Ergonomics SA : Journal of the Ergonomics Society of South Africa 23, pp 20 –27 (2011)More Less
The investigation of health and safety (H&S) climate has received a lot of research attention in the field of occupational health and safety (OHS). The importance of two H&S dimensions that contribute to the H&S climate were studied. The effect of leadership, top management commitment to health and safety (H&S) and supervisor H&S leadership, and work pressure were examined as predictors of H&S behaviour amongst construction workers in South Africa. A descriptive design was used and a cross-sectional self-administered survey questionnaire was completed by 282 construction workers. The scales used were found to be reliable and valid. The results indicate the importance of considering the interaction between the two aspects of leadership in explaining H&S behaviour.

Many construction injuries are musculoskeletal related in the form of sprains and strains arising from the handling of materials, which are specified by designers, which in turn constitutes the direct influence of designers on construction ergonomics.
The paper presents the results of a study conducted among delegates attending two 'designing for H&S' (DfH&S) seminars, the objectives of which were to determine their level of knowledge, perceptions, and practices relative to the mass and density of materials. The study was conducted using a survey questionnaire circulated to what effectively constituted captive convenience sample strata.
The following constitute the salient findings: the level of knowledge relative to the mass and density of materials is limited; designers generally do not consider the mass and density of materials when designing structures and elements and specifying materials; to a degree designers do appreciate that the mass and density of materials impacts on construction ergonomics; designers rate their knowledge of the mass and density of materials as limited as opposed to extensive, and designers appreciate the potential of the consideration of the mass and density of materials to contribute to an improvement in construction ergonomics.
Conclusions include: designers lack the requisite knowledge relative to the mass and density of materials; designers are thus precluded from conducting optimum design hazard identification and risk assessments, and tertiary built environment designer education does not enlighten designers relative to construction ergonomics.
Recommendations include: tertiary built environment designer education should construction ergonomics; professional associations should raise the level of awareness relative to construction ergonomics, and design practices should include a category 'mass and density of materials' in their practice libraries.
