including those truths that seem unrelated to everyday use;
we have seen that all truths, at least those we can understand,
are so interconnected that we cannot consider any of them
totally useless without some imprudence.”

Abstract: Let a population be composed of members of a criminal organization and judges of the judicial system, in which the judges can be co-opted by this organization. In this article, a model written as a set of four nonlinear differential equations is proposed to investigate this population dynamics. The impact of the rate constants related to judges’ co-optation and ex-convicts’ recidivism on the population composition is explicitly examined. This analysis reveals that the proposed model can experience backward and transcritical bifurcations. Also, if all ex-convicts relapse, organized crime cannot be eradicated even in the absence of corrupt judges. The results analytically derived here are illustrated by numerical simulations and discussed from a crime-control perspective.

Abstract: An epidemiological model considering pro and anti-vaccination groups is proposed and analyzed here. In this model, susceptible individuals can migrate between these two groups due to the influence of false and true news about the safety and efficacy of vaccines. From this model, written as a set of three ordinary differential equations, analytical expressions for the disease-free steady state, the endemic steady state, and the basic reproduction number are derived. It is analytically shown that a low vaccination rate and no influx to the pro-vaccination group have similar impacts on the long-term amount of infected individuals. Numerical simulations are performed with parameter values of the COVID-19 pandemic to illustrate the analytical results. A possible relevance of this work is discussed from a public health perspective.

3. Harari, G.S.; Monteiro, L.H.A. A note on the impact of a behavioral side-effect of vaccine failure on the spread of a contagious disease. Ecological Complexity. v.46, p.100929, 2021.
Abstract: Vaccines save lives; however, no vaccine provides complete immunity for all vaccinated individuals. Thus, some individuals remain susceptible to the contagious disease against which they were vaccinated. By relying on the supposed acquired immunity, these individuals can reduce the self-imposed prevention measures and, as a consequence, they can involuntarily promote the spread of the infection. Here, such individuals are taken into account in an epidemic model based on ordinary differential equations. Depending on the parameter values related to contagion and vaccine efficacy, a less responsible behavior post-vaccination can increase the basic reproduction number of the disease as compared to the case with no vaccine. This result is discussed by considering the current COVID-19 outbreak.

Abstract: Knowledge should represent the main competitive advantage of organizations. The ability to handle and treat knowledge, enabling its generation, capture, distribution, and sharing, is a key ingredient to its success. The generation and management of organizational knowledge involve several factors, such as processes, cultural aspects, organizational structure, support infrastructure, and the scope of knowledge. The development of this paper highlights the different approaches and peculiarities of each culture reflected in the treatment of generation and management of knowledge for organizational projects. We specifically compare the generation and management of organizational knowledge under the Jewish and Japanese visions. In the conduct of this research, bibliographic texts of the theories of generation and organizational knowledge management were used, with specific examples of the theoretical basis of the corporate model in the Japanese culture and, considering that there are no similar theoretical studies in the Jewish culture, we use pieces of evidence in examples of texts of Jewish culture to demonstrate the way that Jewish culture creates, preserves and manages its knowledge. Besides, we conducted interviews that further improved this research.

Abstract: Aware of the importance of the impressive technological advances of the last centuries for modern life, a growing group of people with university education and knowledge of Jewish culture felt the need to provide a language in tune with our time and, concomitantly, maintain the original content, an interface between Jewish and contemporary cultures. This publication fills a cultural gap of great relevance to all who appreciate friendly, pleasant reading and brings together authors of great versatility and deep knowledge in their respective fields.
