«At a certain point, I realized that there's a
percentage of the
population that no matter what you do or say, they're just not going to like you, and it's beyond your
control,» Levy says.
If we grow more food, to reduce hunger, this may simply lead to more people and the continuation
of the same
control in the system which is the same
percentage of the
population hungry.
Most introduced species are not able to do so, but a small
percentage can, benefiting from the lack
of natural
controls like predators, competition, and climate fluctuations that would otherwise keep their
populations in check.
Also, we used objective approaches to quantify neighbourhood attributes that allowed us to partially
control for potential reverse causality due to depressed individuals tending to exhibit negative cognitive bias resulting in negative thoughts and perceptions.65 Residential self - selection bias is likely to be a trivial source
of reverse causality in this study because Hong Kong's high levels
of population density (6760 people / km2) and low
percentage of developed land (less than 25 %) 66 limit most residents» choice
of accommodation and 37 %
of Hong Kong older adults live in public rental housing.67 Given the satisfactory response rate and the level
of similarity in depressive symptoms and sociodemographic characteristics
of participants recruited from two types
of recruitment centres, the findings from this study are likely to be generalisable to the
population of Chinese Hong Kong older adults matching the study eligibility criteria and other
populations of older adults living in similar ultra-dense metropolises
of Southeast Asia.
