Background
Undergraduate engineering students require exposure to an appropriate level of practical activities to complement the theory delivered in their course. This not only serves the purpose of catering to students’ different learning styles but in contributing to developing practical skills important to achieving an adequate level of job-readiness. The mode by which practical activities are implemented can vary widely across different units of study and different institutions. Electronics practicals within the School of Engineering at Deakin University have traditionally involved the construction and analysis of bread board circuits. Recently however, the practicals have changed to utilise modern computer-integrated Lab Volt FACET board equipment.


Purpose
This paper discusses electronics practicals using two very different types of laboratory equipment and reports on student perceived efficacy. The aim of the study is to gain an understanding of student perceptions so as to be able to refine the practicals to increase student engagement.

Design / method
This paper discusses two very different types of laboratory equipment employed in electronics practicals within the School of Engineering at Deakin University. This study focuses on students in electronics-related engineering disciplines and their perceived efficacy of the different equipment with the aim of providing valuable insight regarding student engagement. Survey data was collected from first and second year students who had completed successive classes using the different types of laboratory equipment.

Results
When compared with the electronics practicals and equipment previously used at Deakin University, the Lab Volt FACET boards provide a well-structured and resource efficient method for conducting practicals. The preliminary survey results indicate that there are mixed preferences for which type of laboratory equipment students perceive to be the better learning tool. The results also indicate that these perceptions appear to align with students in specific disciplines. These observations suggest that discipline specific characteristics of students are an important consideration in achieving improved student engagement and a positive learning experience.

Conclusions
The outcomes of the preliminary study suggest that there are discipline specific characteristics which affect students’ perceptions of the efficacy of laboratory equipment. These outcomes will assist Deakin’s School of Engineering to refine the use of the Lab Volt FACET board laboratory equipment to achieve improved student engagement. Future research will build upon these findings to investigate expectations of students in different disciplines and whether there is a difference in preferred learning and any correlation to student perceptions.

With the spectacular rise of the Chinese and Indian economies the accompanying growth in these two countries' construction sectors justifies more understanding. There is, however, a lot of unknowns about the two countries' construction sectors from a comparative perspective. This study attempted to identify and compare the comparative/competitive advantages of the two fast-growing economies in construction in pursuit of policy and management implications, which can benefit not only the two countries but also other developing countries. In this regard, a comparative advantage framework and Porter's Diamond Framework were applied to analyze the relative advantages of the Chinese and Indian construction sectors. The comparative analyses showed that China appears better endowed in labor with high productivity. Government intervention was identified as benefiting Chinese firms with support for the development of human resources. China also benefits from superior access to a wide range of inputs, including equipment, construction materials, and technology. The existence of large corporate champions provides scale of economy and contributes to the advantage of the construction sector of China. In contrast, India benefits from the increased competitive rivalry thanks to its more hands-off government policies that focus primarily on providing a good business environment with a favorable tax system, market entry policies, laws and regulations, and code/standard systems. The differences identified provide policy implications to the decision makers of the two countries in further developing their construction sectors. © 2014 American Society of Civil Engineers.

Climate change is a severe threat to human development. Environmental protection and economic growth are two significant dimensions of promoting sustainable global development. In this research, a two-step procedure has been applied to investigate carbon productivity, which is deemed an appropriate indicator to measure sustainable development in conjunction with carbon reduction and production advancement. A decomposition method with the Log Mean Divisia Index has been applied to explore the factors influencing carbon productivity change, including technological innovation and regional adjustment. The carbon productivity of the Australian construction industry from 1990 to 2012 was then investigated. Research results indicate that carbon productivity in Australian construction had increased significantly and could be further improved. Technological innovation has played an important role in promoting carbon productivity, while regional adjustment has remained roughly steady. Based on correlation analyses, scale of the construction market and stock of machinery and equipment had shown weak correlations with carbon productivity changes, and it was clear that improvement in carbon productivity could benefit capital productivity and investment return. The research has systematically defined carbon productivity and for the first time measured it for the construction industry. The results are expected to assist construction industries worldwide to investigate productivity performance and to identify the influencing factors for improving development sustainability.

Previous studies have proved the application of Building InformationModelling (BIM) can lead to greater efficiencies. Slowly adopting newtechnologies and limited technological innovation are criticised for theconstruction industry. In this paper, we present research that examinesthe practices of BIM technologies for the clash detection and coordination among building structure, equipment and pipelines, quantity statistics and construction simulation in a construction project in China. The BIM application significantly promotes the abilities to achieve construction schedule, quality, budget, and scope objectives in the project. The technological capabilities of BIM, the illegal issues of BIM outputs and developing cooperative project management culture are needed in order to promote BIM application in the construction industry.
