Statistical Thinking in Computer-Based Learning Environments

The theme of technology is particularly important for statistics education because of the role of technology in changing views of statistical knowledge, pedagogy and learning. The interactive multimedia technology of today allows for the creation of powerful learning environments where the focus is on the process that produced the data and its associated variation and the statistical thinking required to solve the problem. However, despite this optimistic view, students' self‐regulation and intrinsic motivation seem to be key concepts for learning in complex interactive computer‐based learning environments. We conclude with observations of teachers and students working with applets. More of these evaluations should be published and/or made available to the statistical community so that both positive and negative teaching experiences can be shared.

An assessment and ranking of barriers to doing environmental business with China

The transfer of environmental goods and services to China will increasingly be of importance to developed nations as the demand for environmental management services increases in China. A review of the literature on technology transfer to China revealed a range of well recognized and commonly known constraints to transferring technologies to China. There were gaps in the literature in relation to the concerns that environmental professionals have regarding technology transfer to China, as there is limited information on the transfer in environmental goods and services to China. A survey of the non‐trade barriers and their practical impact on the transfer of environmental technologies and goods and services to China, focusing on Australian suppliers, was undertaken to address these gaps. The survey, which was developed from barriers to technology transfer already described in the extensive research addressing the wider issues of technology transfer to China, targeted environmental professionals but also included other professionals with interests in transferring environmental goods and services to China. From the survey, the highest priority barriers to transferring environmental goods and service to China were identified, and those that are most likely to limit Australian vendors of environmental goods and services in their technology transfers to China were protection of intellectual property (IP), limitations of the rule of law, fragmentation and bureaucracy of the Chinese government and establishing appropriate level of ownership (of environmental goods and services providers in China). Examples of Australian experience were also examined, which confirmed these barriers to providing the needed technology and innovation to manage China's increasing environmental impacts. The research also shows that the barriers identified do not appear to be unique to transfer of environmental goods and services but rather generic to the transfer and adoption of Australian technology into China.

Does Trade,Technology, or Education Expel Traditional Sectors? Some Evidence from the Collapse of the Silk Sector in South Korea*

Rapid economic growth and development often drives out traditional activities. We determine how increased trade, technology, and access to education in South Korea led to the collapse of its silk sector. Results show that although the imports of silk yarn and fabric reduced domestic silk output and prices, trade liberalization was not the sole contributor to the collapse. Inelastic labor demand for unskilled workers, skill‐biased technology, and especially increased access to education all led to a sharp rise in the relative wage of unskilled workers, and the ensuing rise in production costs contributed to the silk sector's collapse.

Mobile technology usage and B2B market performance under mandatory adoption

This paper investigates the relationship between mandatory adoption of mobile information technology and market performance in the business-to-business (B2B) setting. This study presents and tests the B2B technology satisfaction model (TSM), including perceived loss of control as the mandatory technology acceptance-specific variable. The results of this study reveal that integrating perceived loss of control with user satisfaction and the TAM (technology acceptance model) in a single model can better explain the B2B market performance model. The empirical results suggest that perceived loss of control has a negative effect on user satisfaction and perceived market performance is influenced by user satisfaction and perceived usefulness. Managerial implications of the study are discussed.
