Municipal residents
Area of Science:
- Environmental Science
- Urban Planning
- Behavioral Economics
Background:
- Urban solid waste recycling is a complex system.
- Resident behavior significantly impacts recycling sectors.
- Previous models overlooked individual decision-making.
Purpose of the Study:
- To model urban residents' recycling choices.
- To analyze the influence of regret-joy and personality.
- To evaluate policy impacts on formal and informal recycling sectors.
Main Methods:
- Multi-agent-based modeling (MABM).
- Simulation of agent decision-making under various strategies.
- Introduction of psychological factors (regret-joy) and personality traits.
Main Results:
- Without government intervention, 60% of residents favor the informal recycling sector (IFRS).
- Formal recycling sectors (FRS) struggle due to low incomes.
- Subsidies improve FRS income more than regulations, but neither curbs IFRS.
- Combined subsidy and regulation policies shift 60% of residents to FRS, boosting its profit and market share.
Conclusions:
- Individual behavioral decisions are critical in waste management.
- Single policies are insufficient to boost formal recycling.
- Integrated policies are essential for effective urban waste recycling and management.

3.0K
The recycling endosome, also known as the endosomal recycling compartment (ERC), is a part of the slow-recycling process of the endocytic pathway. Molecules internalized through receptor-mediated endocytosis are either degraded in the lysosomes or are recycled to the plasma membrane through the fast- or slow-recycling route.
The recycling endosome is not a single organelle but an extensively tubulated network of recycling pathways. It functions in storing molecules or transporting them across...

Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...
