“…On the other hand, external dynamics may impoverish/take out of poverty people, which is also a risk factor in front of a CD. Note that the transmission of the NCD could still be formulated considering more sophisti-cated functional terms [23], [21], but we disregard this approach here to keep the model formulation minimal as mentioned. The dynamics of the transmissible disease is somehow similar to (but not exactly) the classical SIS model [2] with density-dependent transmission.…”

This work presents a model combining the simplest communicable and non-communicable disease models. The latter is, by far, the leadingn cause of sickness and death in the World, and introduces basal heterogeneity in populations where communicable diseases evolve. The model can be interpreted as a risk-structured model, another way of accounting for population heterogeneity.Our results show that considering the non-communicable disease (in the end, heterogeneous populations) allows the communicable disease to become endemic even if the basic reproduction number is less than 1. This feature is known as subcritical bifurcation. Furthermore, ignoring the noncommunicable disease dynamics results in overestimating the reproduction number and, thus, giving wrong information about the actual number of infected individuals. We calculate sensitivity indices and derive interesting epidemic-control information.

“…Instead, most have focused on identifying the factors that influence public insecurity in a city and their level of impact using a multidimensional statistical method (e.g., [14]- [16]. Among these works, some tend to assess the performance of various factors or schemes through a cost function, this function merges several measures that influence the public security in a city [17]. For example, costs could be calculated according to the perspectives of the victims, government, and society, such as lost productivity, pain and suffering, medical expenses, and the criminal justice system being integrated into cost models [18].…”

Multicriteria Decision Model to Support the Evaluation of Common Jurisdiction Violence in the Capital Cities of the States of Mexico

et al. 2023

The capital cities of the states of the Mexican Republic present a considerable heterogeneity in terms of their level of public security, so their correct characterization is an essential requirement, but not sufficient, for the elaboration of public policies for the prevention of crimes in the common jurisdiction. In this paper, we propose a multicriteria decision model based on the hierarchical ELECTRE III method that assists in how a policymaker can carry out this task. The objective of the work is to measure and compare the incidence of crimes of common jurisdiction in the capital cities of the states of the Mexican Republic. This model compares public security in 31 capital cities, adapting the situation as a multicriteria ranking problem to order the different capitals by their level of public security. The results showed that the model could identify the level of comprehensive public security of a capital city compared to the rest. Similarly, it also shows the disparities of this phenomenon between capital cities in relation to high, medium and low impact crimes.
