Metastability, Criticality and Phase Transitions in brain and its Models

This essay extends the previously deposited paper "Oscillations, Metastability and Phase Transitions" to incorporate the theory of Self-organizing Criticality. The twin concepts of Scaling and Universality of the theory of nonequilibrium phase transitions is applied to the role of reentrant activity in neural circuits of cerebral cortex and subcortical neural structures

Interests Diffusion in Social Networks

Understanding cultural phenomena on Social Networks (SNs) and exploiting the implicit knowledge about their members is attracting the interest of different research communities both from the academic and the business side. The community of complexity science is devoting significant efforts to define laws, models, and theories, which, based on acquired knowledge, are able to predict future observations (e.g. success of a product). In the mean time, the semantic web community aims at engineering a new generation of advanced services by defining constructs, models and methods, adding a semantic layer to SNs. In this context, a leapfrog is expected to come from a hybrid approach merging the disciplines above. Along this line, this work focuses on the propagation of individual interests in social networks. The proposed framework consists of the following main components: a method to gather information about the members of the social networks; methods to perform some semantic analysis of the Domain of Interest; a procedure to infer members' interests; and an interests evolution theory to predict how the interests propagate in the network. As a result, one achieves an analytic tool to measure individual features, such as members' susceptibilities and authorities. Although the approach applies to any type of social network, here it is has been tested against the computer science research community. The DBLP (Digital Bibliography and Library Project) database has been elected as test-case since it provides the most comprehensive list of scientific production in this field.Comment: 30 pages 13 figs 4 table

New labour and new surveillance: Theoretical and political ramifications of CCTV implementation in the UK

This paper examines the implications of New Labour's approaches to crime and disorder on CCTV implementation. It concentrates on the usage of CCTV as one of the government's many initiatives, which are intended to address crime and disorder, including the fear of crime. In particular, the impact of the 1998 Crime and Disorder Act (CDA) - the cornerstone of this government's approach to crime reduction - on the generation of such strategies is examined. The paper revisits neo-Marxist and Foucauldian analyses of the so-called surveillance society through an appraisal of the complex relationship between structure and agency in the formulation and implementation of anti-crime and disorder strategies. Drawing on fieldwork data the paper considers the activities of practitioners at a local level by focusing on the influence of central government, local communities and 'common sense' thinking based on certain criminological theories. It is argued that a myriad of micro-level operations, obligations, processes, managerial concerns (particularly conflict resolution and resource issues), structures and agency - as well as the indirect influence of central government - shape CCTV policy. Ultimately, the creation of new local policy contexts under the CDA emphasise the need to consider incremental and malleable processes concerning the formulation of CCTV policy. In turn, this allows a re-examination of theoretical accounts of surveillance, and their attendant assumptions of sovereign or disciplinary power

An actor-network theory (ANT) approach to Turkish e-government gateway initiative

There are various models proposed in the literature to analyze trajectories of e-Government projects in terms of success and failure. Yet, only the Actor-Network Theory (ANT) perspective (Heeks and Stanforth, 2007) considers the interaction factors among network actors and actants. This paper proposes the ANT for approaching to the Turkish e-Government Gateway initiative as a case study. In doing so, it provides valuable insight in terms of both local and global actor-networks which surround the initiative

Education, Cultural Change, Territory. The Third Sector's Innovation. An Italian Case Study

This contribution proposes a theoretical-empirical reflection on the relationship among the three sociological concepts identified by the authors as essential dimensions of the innovation: cultural change, education, and territory. The aim is to illustrate the complex relationship among these dimensions and the implications involved in terms of s oci ologi cal perspectives and research tools, on the basis of the analysis of an emblematic case study: “FQTS”, Italian acronym of the project of Education of Executives and Leaders of the Third Sector in the Southern Italy. In particular, this investigation will be aimed at: (re)defining sociological concepts considered fundamental for the study of innovation; reconstructing the main empirical evidence emerging from the analysis of the case study; and summarizing the relevance of the research results, in terms of new themes and sociological perspectives, as well as of methodological questions
