The European Network on Psychoeducational Assessment, Intervention and Rehabilitation (ENPAIR) focuses on two related topics. The first is research regarding psychological and psychoeducational assessment procedures. The second is research on development and implementation of psychological and psychoeducational…

This thesis is divided into two parts. In Part I we study metastability properties of queue-based random-access protocols for wireless networks. The network is modeledas a bipartite graph whose edges represent interference constraints. In Part II we study spectra of inhomogeneous Erdős-Rényi random…

The Latin America and Caribbean Security and Intelligence Network (LACSIN) brings together scholars, practitioners, government agencies and the diplomatic community to develop novel and interdisciplinary approaches to addressing key areas of security and intelligence in Latin America and the Caribbe…

Intelligence of the crowd, or in other words, intelligence of a large, random collective, exists mostly in social media platforms such as twitter. The collective does not comprise (at least not necessarily) experts on crises, just regular people mostly. Nevertheless, there is valuable intelligence to…

Drawing on insights from past and contemporary scholars and world leaders, the report explores the concepts of a new social contract, a new global deal, and networked and inclusive multilateralism introduced recently by Secretary-General António Guterres to help the United Nations better grapple with…

Dr. Cátia Antunes and prof. Jos Gommans both edited and contributed to this interesting book, that consists of articles that offers a new insight into the macro and micro worlds of the global Dutchman in Asia.
