“…It is an idealization of the real situation in which the complex process is reduced to its essential properties [48]. Therefore, the proposed model can be extended in various ways, by assuming that information decreases at each transmission event while it is gradually lost within each individual and eventually disappears if not refreshed [37,49], a dynamics that would be most appropriate especially in some rural communities in the developing world where the major means of communication is by word of mouth.…”

There is significant current interest in the application of media/psychosocial effects to problems in epidemiology. News reporting has the potential to reach and to modify the knowledge, attitudes, and behavior of a large proportion of the community. A susceptible-infected-hospitalized-recovered model with vital dynamics, where media coverage of disease incidence and disease prevalence can influence people to reduce their contact rates is formulated. The media function is incorporated into the model using an exponentially decreasing function. Qualitative analysis of the model reveals that the disease-free equilibrium is locally asymptotically stable when a certain threshold is less than unity. Numerical results show the potential short-term beneficial effect of media coverage.

“…It is worth noticing that an approach similar to the one presented here was proposed in [25] for the rumor spreading model [35], with the difference that the authors considered a static network mimicking the fact that agents would remember their connections and explore only a fixed subset of the network. Recent results on the effects of social memory and the heterogeneity of social ties on spreading phenomena suggests that future work may benefit from including more realistic partner selection mechanisms also in temporal networks to better reflect what is observed in real social networks [30,[36][37][38].…”

Committed activists and the reshaping of status-quo social consensus

et al. 2015

The role of committed minorities in shaping public opinion has been recently addressed with the help of multi-agent models. However, previous studies focused on homogeneous populations where zealots stand out only for their stubbornness. Here, we consider the more general case in which individuals are characterized by different propensities to communicate. In particular, we correlate commitment with a higher tendency to push an opinion, acknowledging the fact that individuals with unwavering dedication to a cause are also more active in their attempts to promote their message. We show that these activists are not only more efficient in spreading their message but that their efforts require an order of magnitude fewer individuals than a randomly selected committed minority to bring the population over to a new consensus. Finally, we address the role of communities, showing that partisan divisions in the society can make it harder for committed individuals to flip the status-quo social consensus.

“…Siguiendo esas discusiones de los impresos como literatura publicada al servicio de la difusión de las ideas en la ciencia, Goffman & Newill (1964) propusieron que el proceso de comunicación de las ideas que circulan en una determinada comunidad científica sea examinado como si fuese la transmisión de una enfermedad infecciosa; es decir, en términos de un proceso epidémi-co de dos factores que describan el contacto individual o grupal sin tomar en consideración la complejidad que tiene una epidemia cuando aparece en una situación concreta, ya que un modelo es apenas una idealización de la situación real en la que la complejidad de los procesos son reducidos a sus propiedades esenciales. En el modelo epidémico esas propiedades esenciales son:…”

EL OBJETIVO DE ESTE TRABAJO ES ESTUDIAR EL MODELO EPIDÉMICO COMO UN PROCESO DETERMINÍSTICO REPRESENTADO POR UN SISTEMA DE ECUACIONES DIFERENCIALES. ESTE MODELO ES DESPUÉS APLICADO A LOS AUTORES PRODUCTORES DE LITERATURA SOBRE LA LEY DE LOTKA DESDE 1922 HASTA 2005. SE OBSERVA QUE ESTA SUB-ÁREA DE LA BIBLIOMETRÍA ENTRÓ EN UN PROCESO EPIDÉMICO A PARTIR DE 1965, QUE ÉSTE TIENE UNA ALTA TASA DE AUTORES TRANSEÚNTES, Y QUE LOS AUTORES QUE PUBLICAN EN IDIOMAS DIFERENTES AL INGLÉS ENCONTRARON EL ÁREA YA EN UN ESTADO EPIDÉMICO.
