The use of Engineered Wood Systems (EWS), especially mass-timber, as a structural alternative or complement to steel and concrete is gaining interest and acceptance across different sectors of architecture, engineering, and construction, including in high-rise buildings. Focussing on the Australian context, this study examines the levels of adoption and barriers to using timber as a primary structural material in multi-storey buildings. Data collected from semi-structured interviews with stakeholders at the forefront of adoption in structural design, construction, and property development indicates that timber in multi-storey projects in Australia still faces industry-wide challenges. Designers' awareness and attitudes towards timber adoption are generally positive and suitable for flagship projects, including tall buildings, but for enduring and widespread impact, long-term investment in education within and outside the range of stakeholders already committed to promoting timber adoption is needed.

Research related to Web-based learning (WBL) has grown exponentially in the last decade. Scholars have explored a variety of areas related to WBL, including techniques, strategies and best practices. One area of particular interest to scholars is the potential of WBL to support and facilitative collaborative learning. Despite the continued exploration, there continues to be a concern related to the theoretical foundations of WBL. The purpose of this article is to explore how different theories may be used to guide research and inform practice in online collaborative learning. We integrate the major points drawn from current research and theory from a variety of perspectives so as to gain a better understanding of how learning is enabled by asynchronous modes of online collaborative learning. We then use this understanding to identify opportunities and challenges for theory development and research in WBL.

The coronavirus disease 2019 (COVID-19) pandemic may be stressful for people. Public health actions, such as social distancing, can make people feel isolated and lonely and can increase stress and anxiety. As a result, there is a growing interest towards various materials to relieve stress. Thus, the present study aimed to investigate the anti-stress effects of ethanol extract of Ziziphus jujuba in PC12 cells treated with corticosterone and its underling mechanisms. Furthermore, the viability of the cells, the apoptosis of the cells, the level of phosphorylation of extracellular signal-regulated kinases (p-ERKs) expression were measured by MTT assay, LDH assay, Hoechst staining assay and western blotting. Our results showed that the extract of Ziziphus jujuba reversed corticosterone-induced damage in PC12 cells, which increased cell viability, decreased LDH release, and attenuated corticosterone-induced apoptosis as compared with the corticosterone-treated group. Therefore, these data suggest that the extract of Ziziphus jujuba could be a good candidate for development as a functional food supplement in the improve the anti-stress effect.

Corporate social responsibility (CSR) is of increasing interest to both industry practitioners and academics because of increasing public awareness of environmental, economic and social sustainability. The last decade witnessed a large number of studies on the development of CSR principles and the implementation of CSR in various industries such as the mining industry, oil industry and food industry. However, there is limited number of CSR studies focusing on the construction industry. Considering the critical role the construction industry plays in achieving economic, social and environmental sustainability, it is imperative to extend the current CSR research to the construction sector. This paper provides a critical review of literature related to corporate social responsibility in construction context. A special focus is placed on the current practice adopted by the industry to be socially responsible. A research agenda is set up to tackle this critical issue.

We are designed to solve cyber motion sickness, an important task that must be addressed for the growth of the virtual reality content industry. Not only the industry but also academia are paying a lot of attention. However, despite long interest and research on the phenomenon of cyber motion sickness, a solution has not been drawn. This is deeply related to the lack of tools that can effectively measure cyber motion sickness. Therefore, in this paper, prior studies on cyber motion sickness were analyzed to develop a tool that can effectively measure cyber motion sickness when users experience immersive virtual reality. The measurement method of cyber motion sickness used in previous studies, each characteristic and limitation, and common factors related to cyber motion sickness were analyzed. Each of the related factors was derived as sub-factors. Based on the analyzed contents, an effective cyber motion sickness measurement evaluation tool model in immersive virtual reality was presented. It is expected that the evaluation tool model can be used for the study of cyber motion sickness.
