Results show that the method is easy to be used to identify the most crucial areas of the city, in several domains of application that have been identified. The study can substantially support policy makers in the development of their strategies and in the measurement of the effectiveness of their decisions.展开更多

It has been one of the most hot research topics. Now many corporations have involved in the performance dashboard Architectures related techniques and many performance dashboard Architectures have been put forward. This is a favorable situation to study and application of performance dashboard related techniques. Though interesting, there are also some problems for so many Architectures forms. For to a novice or user with little knowledge about performance dashboard Architectures, it is still very hard to make a reasonable choice. What differences are there for different performance dashboard Architectures and what characteristics and advantages each has? To answer these problems, the characteristics, architectures and applications of several popular performance dashboard Architectures are analyzed and discussed in detail. From the comparison of these Architectures, users can better understand the different performance dashboard Architectures and more reasonably choose what they want.展开更多

The transportation of sputum samples is an efficient method of increasing access to tuberculosis (TB) diagnostics in areas where testing is not currently available. One of the major reasons for the low yield of TB cases in the field was delay in sputum sample transportation to diagnostic laboratories among other factors. Damien Foundation Belgium, carried out a unique sputum riders initiatives in 20 LGAs of Lagos state between Q3-2019 and Q4-2020.
