A taxonomy of heterogeneity and dynamics in particle swarm optimisation

We propose a taxonomy for heterogeneity and dynamics of swarms in PSO, which separates the consideration of homogeneity and heterogeneity from the presence of adaptive and non-adaptive dynamics, both at the particle and swarm level. It thus supports research into the separate and combined contributions of each of these characteristics. An analysis of the literature shows that most recent work has focussed on only parts of the taxonomy. Our results agree with prior work that both heterogeneity and dynamics are useful. However while heterogeneity does typically improve PSO, this is often dominated by the improvement due to dynamics. Adaptive strategies used to generate heterogeneity may end up sacrificing the dynamics which provide the greatest performance increase. We evaluate exemplar strategies for each area of the taxonomy and conclude with recommendations.

Migration and identity in a post-national world

What does post-national identity mean for the control of migration? Katherine Tonkiss engages with the post-national theory of 'constitutional patriotism' and argues in favour of both post-national identity and relaxed migration controls. She explores the implications of such liberalised migration for the dynamics of identity and belonging in local communities, drawing on qualitative research on Eastern European migration to the UK. Illustrated with rich case study material, this book offers a novel contribution to the post-nationalism literature.

Mathematical Packages for Teaching and Research in Internet – Application and Information Support

The paper considers the use and the information support of the most important mathematical Application Packages (AP), such as Maple, Matlab, Mathcad, Mathematica, Statistica and SPSS – mostly used during Calculus tuition in Universities. The main features of the packages and the information support in the sites of the producers are outlined, as well as their capacity for work in Internet, together with educational sites and literature related to them. The most important resources of the TeX system for preparation of mathematical articles and documents are presented.

Criminals and terrorists in partnership:unholy alliance

The nexus between terrorism and organised crime consists in a strategic alliance between two non-state actors, able to exploit illegal markets, threaten the security of individuals, and influence policy-making on a global level. Recent Europol reports have pointed towards the importance of studying the links between organised crime and terrorist groups, and have underlined that the nature and extent of these connections have seldom been addressed from an academic perspective. Considering the degree of dangerousness that both organised crime and terrorism currently represent in the world, the collusion between these two phenomena is of urgent contemporary interest. Basing itself on geographical case-studies, this edited volume aims at contributing to the existing literature in three ways: by enriching the empirical knowledge on the nature of the crime-terror nexus and its evolution; by exploring the impact of the nexus within different economic, political and societal contexts; and by expanding on its theoretical conceptualization.

Neither security nor development? Czech and Hungarian identities and interests in the provincial reconstruction teams in Afghanistan

This article builds on the securitisation and post-development literature and it scrutinises the Czech and Hungarian legitimising discourses of the two countries’ respective Provincial Reconstruction Teams (PRTs) in the Logar and Baghlan provinces of Afghanistan from 2007 to 2013. In spite of the hybrid civil–military character of the PRTs, their security–development nexus was absent and they were respectively securitised and “developmentalised” only indirectly and to a varying extent. The PRTs were mostly justified by the Czech Republic's NATO membership as an identity issue and they were justified as a Hungarian national interest and as both an obligation and an opportunity. Rather than merely importing NATO's arguments as suggested by the previous literature, the depoliticisation and positive connotation of the intervention in Afghanistan was constructed by the domestic NATO-related identities and interests in the Czech Republic and Hungary.
