The contribution of parental nurturing to survival of the young is already taken into account in the definition of reproductive fitness of the parent (we conceptualize the life cycle as going from one reproductively competent adult to the next).
We note that there are significant ongoing efforts, including those focused on a re-conceptualization of the OoL (https://carnegiescience.edu/events/lectures/re-conceptualizing-origin-life), growing out of work on modeling OoL (e.g., the MOL collaboration, https://github.com/ModelingOriginsofLife/March2014WhitePaper/wiki).
Another source of immanency in conceptualizing the life-cycle theory is logical necessity (Poole and Van de Ven, 1995).
How best to conceptualize quality of life associated with anticoagulation management was an ongoing challenge during the scale development process, a particular difficulty being that our experts (as well as the literature) tended to make somewhat finer distinctions (e.g., between limitations versus hassles and burdens) than were typically made by patients.
Conceptualizing what constitute life quality may differ among individuals, individuals in different roles, and cultures.
Researchers have conceptualized quality of life on many levels, and there are multiple views on how it should be defined and measured [ 1].
The World Health Organization conceptualized quality of life as the 'individual's perception of their position in life in the context of culture and value systems in which they live, and in relation to their goals, expectations, standards, and concerns' [ 2].
Chinese beliefs about health and illness management are holistic, woven into the social and cultural fabric of daily life, conceptualized within the context of yin-yang, hot-cold, and dry-wet balances, as well as qi and holism [ 37- 39, 75].
2) Quality of life was conceptualized differently with less emphasize on its physiological aspects.
Inflammation is measured using C-reactive protein; quality of life is conceptualized as happiness with life overall as well as intimate relationships specifically.
