Cross-cultural research in occupational stress and coping has produced a wealth of knowledge. Although advancement has been made, there are still problems to be solved. One of these problems is the confusion generated in the literature by researchers claiming nation or country as representing cultural values, and the use of the two terms interchangeably. It remains unclear whether this practice is correct. The present paper reported on this by using 511 full time employees from Australia, Singapore and Sri Lanka to study occupational stress and coping. Results revealed that cultural value paradigm (i.e., Individualism-Collectivism) was distributed across the three nations, such that over 60% of participants across the three nations were either high or low in both I-C paradigms. The findings also indicated that the relationship between cultural value paradigm and country impacted on stress and coping differently. The study shows that significant differences exist within country, as well as between countries, such that any attempt to equate ‘culture’ with ‘country’ becomes problematic. Therefore, these findings establish that country or nation was not the same as culture values and could not be used interchangeably.

In recent times, light gauge cold-formed steel sections have been used extensively since they have a very high strength to weight ratio compared with thicker hot-rolled steel sections. However, they are susceptible to various buckling modes including a distortional mode and hence show complex behaviour under fire conditions. Therefore a research project based on detailed experimental studies was undertaken to investigate the distortional buckling behaviour of light gauge cold-formed steel compression members under simulated fire conditions. More than 150 axial compression tests were undertaken at uniform ambient and elevated temperatures. Two types of cross sections were selected with nominal thicknesses of 0.60, 0.80, and 0.95 mm. Both low (G250) and high (G550) strength steels were used. Distortional buckling tests were conducted at six different temperatures in the range of 20 to 800°C. The ultimate loads of compression members subject to distortional buckling were then used to review the adequacy of the current design rules at ambient and elevated temperatures. This paper presents the details of this experimental study and the results.

A significant number of children suffer long term psychological disturbance following exposure to a natural disaster. Evidence suggests that a dose-response relationship exists, so that children and adolescents who experience the most intense or extensive exposure to the risk factors for PTSD are likely to develop the most serious and persistent symptoms. Risk factors include gender, age, personality, extent of exposure to the natural disaster, amount of damage to property and infrastructure, witnessing injury or death of others or perceiving a threat to their own life. Knowing these factors enables various strategies to be put in place to decrease the risk of psychological disturbance following the aftermath of traumatic events. Re-establishing a sense of safety, security and normality is important in the aftermath of a natural disaster, and promoting social connectedness, positive family functioning, and effective coping mechanisms can make children more resilient in the face of catastrophic events. This paper examines the risk and protective factors associated with the development of post traumatic stress disorder (PTSD), and considers how schools can use this knowledge to contribute to the recovery effort, and reduce the prevalence of PTSD amongst pupils in the wake of a natural disaster.

Despite more than three decades of research, there is a limited understanding of the transactional processes of appraisal, stress and coping. This has led to calls for more focused research on the entire process that underlies these variables. To date, there remains a paucity of such research. The present study examined Lazarus and Folkman’s (1984) transactional model of stress and coping. One hundred and twenty nine Australian participants with full time employment (i.e. nurses and administration employees) were recruited. There were 49 male (age mean = 34, SD = 10.51) and 80 female (age mean = 36, SD = 10.31) participants. The analysis of three path models indicated that in addition to the original paths, which were found in Lazarus and Folkman’s transactional model (primary appraisal-->secondary appraisal-->stress-->coping), there were also direct links between primary appraisal and stress level time one and between stress level time one to stress level time two. This study has provided additional insights into the transactional process which will extend our understanding of how individuals appraise, cope and experience occupational stress.

Refugees from Sudan are the fastest growing community in Australia. Australian mental health professionals have to be prepared to offer services to this ethnic group along with the other mainstream and diverse consumers. In order to offer culturally competent services, these mental health professionals are required to be familiar with this emerging community. As such a review was undertaken with two main goals. Firstly, the review aimed to educate Australian mental health professionals about the demographics and culture of Sudan, the traumas encountered as a result of the civil war, factors leading to massive exodus, and the difficulties of the transit and post migration phase. Secondly, the review intended to inform Australian mental health professionals about the possible acculturation stress that is manifested in the form of intergeneration and role conflict and marital difficulties. The review highlights that there are few studies addressing acculturation stress of Sudanese refugees, and even fewer on the impact it has on relationships. Future research directions are discussed.

Cold-formed steel beams are increasingly used as floor joists and bearers in residential, industrial and commercial buildings. Their structural behaviour and moment capacities are influenced by lateral-torsional buckling and hence a research study was undertaken to investigate the lateral-torsional buckling behaviour of cold-formed steel lipped channel beams at ambient and elevated temperatures. For this purpose a finite element model of a simply supported cold-formed steel lipped channel beam under uniform bending was developed first and validated using available numberical and experimental results. It was then used in a detailed parametric study to simulate the lateral-torsional behaviour of cold-formed steel beams under varying conditions. The moment capacity results were then compared with the predictions from the current ambient temperature design rules in Australia, New Zealand, American and European codes for cold-formed steel structures. Some very interesting results have been obtained. European design rules are found to be conservative while Australian and American design rules are unsafe. This paper presents the results of finite element analyses for ambient temperature conditions, and the comparison with the current design rules.

Frontline employees constitute one of the key interfaces that service organisations have with their markets. Many strategies to enhance the ability of these employees to satisfy the needs of customers have been proposed. Amongst these, empowering employees has been suggested to enhance the customer orientation of the firm and consequently its effectiveness in serving the market. However, the impact of empowerment in service organisations remains somewhat contentious. This paper examines the role of empowerments an organisational service strategy and identifies its consequences for role stress, job satisfaction and the willingness of service employees to serve their customers.
