(vi) Finally, if we try to assess the economic impact of these two opposing variables, lower budgets and higher Risk Indices
, we can determine that this reduction of conservation budgets does not lead to a real saving, as the cost of the additional accidents was higher (by between 0.7 and 2.2 times).
The potential ecological risk indices monomial (Eir) and multinomial (RI) and biological risk indices monomial (ERM-Qi) and multinomial (mERM-Q) for each station and seasons were identified and given in Table III.
According to the results of monomial potential ecological risk indices (Eir), arsenic posed moderate and considerable ecological risk at F2 and F3 stations.
Also, when we analyzed the difference in the fall risk index between the two groups by excluding those who had a fall history, the mean fall risk indices
were reduced to 30.34[+ or -]16.88 and 22.82[+ or -]10.58 for the non-falling AS patients and healthy controls, respectively.
Drinking water results were evaluated for health risk indices
, while soil and plant for pollution quantification factor.
The researchers found that 70% of transplant centers experienced a decline in either or both of the risk indices
Widely-used measures of disproportionality include: (1) composition index (percentage of students in special education represented by a given group); (2) risk index, (percentage of a given racial/ethnic group that is served in special education); and (3) risk ratio (comparison of the risk indices
of different groups).
A value of 0 for the risk indices means there are no unacceptable risks in the included TPMs, each achieving (or extending beyond) its threshold value.
From the data in Table 1 and Equations 9, 10, and 11, we can derive, for each measurement date, the TPM risk indices for the Category A and Category B TPMs, as well as for the overall TPM Risk Index.
To account for the cumulative effect of many minor risk factors, a number of additive risk indices
were created and became popular.[6-13] All such indices have in common the following principles:
