In my research into Sustainability Engineering, Time Use shows itself to be a very important variable. Together with ecological impacts (Ecological Footprint or Planetary Boundaries), Time Use to meet needs is a required unit of measurement. I am using both Max Neef's theory of Fundamental Human Needs, and Doyal & Gough's theory of Human Need.
In my current paper, I am wanting to make a number of statements, and I would like to know of existing publications that have made similar conclusions:
• People are, at all times, acting to meet their perceived needs
• People are generally not able to distinguish between their actual needs and their perceived needs
• People will always act to minimize the time used to meet their perceived needs, so that the time available to meet their wants are maximized
• People will generally act to maximize the portion of their perceived needs that are met
Are there sources you would recommend?
