Driver Workload Response to In-Vehicle Device Operations

A central concern of Intelligent Transportation Systems (ITS) is the effect of in-vehicle devices (e.g., cell phones, navigation systems, radios, etc.) on driver performance and safety. As diverse and innovative technologies are designed and implemented for in-vehicle use, questions regarding the presence and use of these devices assume progressively greater importance. Further concerns for advanced driver training require us to develop and validate reliable and effective procedures for assessing such effects. This work examines a number of candidate procedures, in particular the evaluation of change in cognitive workload as a strategy by which such goals might be achieved.     

铁钙复合絮凝剂HC211用于钻井废水处理性能研究

探讨了在不同PH值、温度、剂量及酸化预处理条件下，铁钙复合絮凝剂HC211絮凝特性和絮凝效果的好坏。研究表明铁钙复合絮凝剂HC211在PH值为8－10，温度为15℃，剂量在4‰左右有好的絮凝效果。尤其在酸化预处理后，铁钙复合絮凝剂HC211絮凝效果更佳。     

Community‐based water supplies in Cikarang,Indonesia: are they sustainable?

Community‐based water supply (CBWS) is an example of how a community manages common pool resources (CPR). This results in an alternative approach to solve water supply problems in developing countries by enhancing community participation in managing water supply. This research evaluates the sustainability of five CBWS projects in Cikarang, Indonesia by using Ostrom's design principles, with additional sustainability factors found in the Sustainable Development Goal (SDG) on drinking water and groundwater sustainability. Quinn et al. (2007) criteria were used in the analysis, and the results show that the management of four CBWS institutions were absent and one CBWS institution was weak. With regards to the SDG's drinking water target, the CBWS institutions were unable to comply with safe water standards, and in terms of groundwater sustainability, efforts to monitor and sustain groundwater tables were absent. Results from this research suggest that more focus must be placed on water quality and groundwater sustainability for CBWS projects.     

Individual differences in behavioral compliance to warnings representing varying degrees of threat

Research regarding warning compliance has often emphasized the physical aspects of the warning itself. Here, we examine the role of the perceiver in sensation seeking and health orientation as individual difference variables that affect behavioral compliance to a health warning. The experiment used a laboratory-based simulation of a chemistry demonstration that has been used in previous warnings research. In addition, however, individual difference effects of sensation seeking and health orientation were investigated. Among the significant findings were a significant interaction between condition assignment and sensation seeking on compliance outcome and a significant interaction between condition and health orientation. These results indicate that individual difference variables represent significant influences on the degree to which persons comply with warnings.
