Waste collection criticality index in African cities

The paper proposes to define a waste collection criticality index that is based on a quantified census of the current solid waste management situations of 24 African cities. The proposed index allows to compare collection efforts, to draw up a typology of cities and to highlight those where the situation is alarming. Identifying direct and indirect factors that may accentuate the specific problem of uncollected waste provides an interesting context. The exploration of the current context in different African cities has shown a growing interest in the particular issues of uncollected waste. In addition, the specificities related to the composition of waste and the problem of rapid change in lifestyle, as well as inadequate infrastructures require revisions and new perspective into public policy responses. However, decision-making in waste management still needs a dashboard with reliable indicators as well as recent data that is essential for economic analysis and for choosing an appropriate governance method adapted to each city. In this context, the criticality index applied to African cities, has revealed the impossibility of enhancing waste management without improving urban infrastructure and reducing poverty.

On-line Analysis of Marine Water Quality Data Based on Large Electronic Computer

Cong, W.; Guo, J., and Yu, H., 2019. On-line analysis of marine water quality data based on large electronic computer. In: Guido-Aldana, P.A. and Mulahasan, S. (eds.), Advances in Water Resources and Exploration. Journal of Coastal Research, Special Issue No. 93, pp. 47–53. Coconut Creek (Florida), ISSN 0749-0208.In order to make full use of marine resources, develop marine economy and build a powerful marine country, in recent years, the state has focused on the on-line analysis technology of marine water. In order to solve the problems of rapid change of marine environment and difficulty in the detection and analysis of water quality data, this paper presents an online analysis method of marine water quality data based on large electronic computer after comparing various methods of marine water quality detection in China and abroad. This method uses a variety of marine water quality sensors to collect marine water quality data synthetically, and then uses multi-sensor fusion technology to fuse the collected water quality data. Finally, it combines multi-sensor D-S evidence theory data fusion technology with computer to analyze water quality data synthetically online. It is concluded that this method can effectively improve the ability of marine pollution early warning and marine ecological environment protection by real-time comprehensive analysis and research of marine water quality data.

Rapid Change: Nine Information Technology Management Challenges

Information technology is rapidly changing. This increases the complexity of IT management. Previous research hypothesized that rapid change in IT causes eleven different categories of problems for IT managers. The current study developed a survey instrument based on detailed items about such problems from that research. The instrument was mailed to a nationwide sample of 1,000 IT professionals. Two hundred forty-six provided useable data. The data supported and clarified nine of the categories of problems of rapid change in IT. The categories are Vendor Neglect, Vendor Oversell, Acquisition Dilemma, Support Burden, Resistance, Cascading Needs, New Integration, Errors, and Training Demands. The research also offers suggestions for future investigation of the problems and a potential instrument with which to conduct it. Anticipating and planning for the problems may help IT managers avoid project delays and budget overruns.
