Third, The quality of life (QOL) of older people in rural China is worrisome. One report use the 36-item Short Form Health Survey (SF-36) to evaluate the QOL in the older Chinese in Zhejiang, and all scale scores of SF-36 in the rural population were significantly lower than those in...

The FR checklist is a weighted summative scale so it has to be computed manually using Bracha and Burkle’s formula rather than using factor analysis. It has multiple reversed indicators. Ergonomics We could not find a reasonable scale for evaluating home office ergonomics. There is comparatively ...
[50]. In scoring the eight domains and two domains in the SF-12 in this study, the total scores in each domain were transferred to the hundred mark system, and the Z-scores of the eight domains and two domains were calculated. The formula Score = 50+ (domain/Z-value (domain)...
Take the logarithm of the formula and obtain the formula: 𝑙𝑛𝑌𝑖𝑗𝑡=𝑙𝑛𝑓(𝑋𝑖𝑗𝑡,𝛽)+𝑣𝑖𝑗𝑡−𝑢𝑖𝑗𝑡 lnYijt=lnfXijt,β+vijt−uijt (2) In the formula, i represents the exporting country and j represents the importing country. Yijt re...
In Equations (4)–(6), as the porosity of the samples increases, the Biot coefficient increases. For instance, soils have a Biot coefficient equal to 1, while the Biot coefficients of the most sandstone samples are in the range of 0.6–0.8 when the porosity is between 0.15 and 0.2. Biot...
Wi = ∑nk=1 ξi(k) n (6) wi = ∑im=1 Wi m (7) In this article, the grey relational analysis model of a system feature sequence is represented as follows: Xo = {xo(1), xo(2), ··· xo(15)} = {1, 1, ··· 1} (8) In the above formula (5), k: 1, 2, . ...
Table 1. Measurement of variables used in research models. ZSORE and the independent variables: RETA, EBITTA, WCTA, and BVETD in model (1) and model (2) are related to each other by the formula to calculate the value of ZCORE. Thus, to avoid multicollinearity, the authors studied the...
