For exposures that are relatively common, such as household crowding (58% in this population) [44], this study size will be able to detect an odds ratios (OR) for disease of 1.8 in exposed subjects relative to unexposed subjects with probability (power) of 0.8 and type I error ...
According to Vergnaud's (1983) theory of conceptual field, division is a multiplicative concept that is closely connected with multiplication, fractions, ratios, and proportional reasoning. Whereas division is not taught formally in kindergartens and early primary schools in most countries, do children...
Comprised of the number of individuals in an economy who are either working or avail- able for work, a labor force is characterized by age structures, sex ratios, and educational levels. Other descriptors of the labor force are dependency ratios, and the average farmland area per farmer, and...
ratios. Yep. And we’re starting to decode the story of a company’s capital structure. We’re getting there. But it’s not just about the numbers, is it? You’re spot on. There’s more to the picture, right? Numbers alone don’t tell the whole story. Okay. We need ...
Similarly, B_N and A_N represent the proportions in households with lesser influence of RSOA. The results show that after grouping, the changes in the ratio of boys born before and after parents' enrollment become more pronounced. Specifically, in households strongly influenced by RSOA, the ...
individuals are relatively low. Spherical HDL particles exhibit considerable heterogeneity in diameter, ranging from 7 nanometers (nm) to 14 nm [36]. This heterogeneity is also evident in the significant differences among particles in lipid proportions, protein ratios, and types of apolipoproteins ...
Despite the main and support workforces being nearly balanced in terms of proportions, the turnover rates for the support workforce were nearly twice those of the main workforce. 3.3. Crime and Severity- the ‘demand’ on policing Previously, we argued that analysis of the police-crime ...

The equation is similar to CMC but the weighting functions are largely based on RIT/DuPont tolerance data derived from automotive paint experiments where sample surfaces are smooth. It also has ratios, labeled kL (lightness) and Kc (chroma) and the commercial factor (cf) but these tend to ...
