Technical research innovations of the US national security system

Rorigo Fileto Maciel and Professor Saskia Bayerl’s paper published in the Scientometrics

Rodrigo Fileto Maciel and Saskia Bayerl, from CESAM, have recently published an article in Scientometrics. The article is titled Technical research innovations of the US national security system and is co-authored with Marta Macedo Kerr Pinheiro from the Universidade FUMEC Belo, Brazil.

In the article, they considered the US national security system (US NSS) as a sectoral system of innovation (SSI). Their goal was to identify and understand the evolution of the technological trajectories promoted by the system with special attention to the intelligence-related sub-system. They found that borders of the US NSS as sectoral system of innovation are very broad, with interdependencies and complementarities between and within the technological paradigms. The technological paradigms and their respective science classification are represented in the map of science below.

In the paper they highlighted, that the intelligence related research is very focused towards providing new recognition capabilities for the current computers or even the development of a new computer based on quantum mechanics. They then further illustrated that the scientometric approach offers possibilities to understand the dynamics and evolution of technological paradigms and SSI.

Rodrigo was a visiting PhD candidate at CESAM last year and wrote the paper together with Saskia, the Research Associate at CESAM and Professor of Digital Communication and Security at CENTRIC, Sheffield Hallam University, during his stay.

Scientometrics is an International Journal for all Quantitative Aspects of the Science of Science, Communication in Science and Science Policy. The journal’s emphasis is placed on investigations in which the development and mechanism of science are studied by statistical mathematical methods.


The Centre of Excellence in Public Safety Management (CESAM) at RSM, Erasmus University Rotterdam, aims to promote and foster the professional development and management of public safety organisations, on an international level. It targets a clear and direct impact of academic research on public and private sector organisations in the field of public safety.
