After initial failed forays into healthy "meals" – salads and other nonsense – McDonald's realised that what the punters want is the fantasy of health and quality, mediated through fancy lettuce and dusty sourdough buns, not the sour apples-in-bags terror of the real.
The study also demonstrated that depressive levels and sleep quality mediated the relationship between the emotional burden of headache and the frequency of attacks.
The analyses also assume that dietary fat quality mediates its effects on CVD risk solely via effects on lipids.
However, contrary to model 1, the role of perceived quality mediating the relationship between customer satisfaction and customer loyalty intention was not supported in model 3.
They are computed using MILP and as a result, this technique can be applied to genome-scale networks, a quality mediated by the fact that computation time climbs only polynomially with respect to network size.
The investigated research models included three hypothesized relationships of these three constructs: 1) patient satisfaction mediates perceived quality and patient loyalty intention; 2) perceived quality and patient satisfaction have an equivalent impact on patient loyalty; and 3) perceived quality mediates patient satisfaction and patient loyalty intention.
Plach et al. [ 18] found that purpose in life was predicted by functional status, with social role quality mediating the effect of functional status on purpose in life and moderating the effect of pain on purpose in life, whereas Schleicher et al. [ 19] found significant univariate associations between pain and fatigue on the one side and purpose in life on the other side.
Similarly, Vojtech et al. [9] assumed that the negative impact of Bt corn on the parasitoid Cotesia marginiventris was host-quality mediated when it developed inside susceptible Spodoptera littoralis larvae that had fed on transgenic Bt corn.
Unlike predators, which are often generalists and feed on several different prey species, parasitoids usually complete their development on a single host individual and are likely to be adversely affected if their Bt susceptible hosts are treated with Bt toxin and are weakened or killed [26], a phenomenon usually referred to as host-quality mediated effects.
We hypothesized that mood disorders, i.e., depression and anxiety, and poor sleep quality would mediate the association between headache and related-disability with the frequency of headaches.
