The effects of selection bias are minimized to some extent by the cohort design, which uses an extensive matching process to account for age, gender, residence, smoking history, and reference period.
Based on the overall results produced by the examined model combinations and taking into account that the reference period (1981 2000) includes a severe drought period (Loukas and Vasiliades 2004) which significantly affected the water balance of PRB, the anticipated effects of climate change in water resources availability and management are expected to be severe.
We focus on principal status because this accounts for the preponderance of the reference period of 365 days preceding the date of survey.5. Figure 1 shows the representation of each demographic group among sector-specific wage earners.
If one accounts for some underreporting in the reference period and assumes 7 cases as reference, 12 cases would be the threshold.
Net-net accounting relates the accountable emissions or removals to a defined reference year or reference period, by which a specific level for accountability is introduced and only "additional" efforts to exceed or failures to meet past emission/removal levels are honoured.
If the national baseline rate is less than half of the global baseline rate in the reference period, then the difference is accounted as avoided forest conversion in the commitment period.
Because reporting conventions changed several times during our reference period, we had to limit our accounting to 17 metals and 17 non-metallic minerals.
Here the assumption is made that non-human-induced impacts on the reference period remains at similar levels for the accounting period, while any change between the two periods is assigned to human-induced impacts.
Second, it is also important to take into account the space-time extent (i.e., reference area and reference period) over which the past seismicity is smoothed.
This paper presents the theoretical expressions of the cumulative distribution function (cdf) of the maximum intensity during a reference period taking the temporal variation of load intensity into account.
The approach that we propose is based on the principle that the accounting of forest mitigation outcomes should reflect fully the impact of changes in forest management practice relative to a historical reference period.
