Understanding Art-Making as Documentation

Though typically arts information professionals are concerned with the documentation of artwork, this conceptual paper explores how art-making itself can be considered a form of documentation and finished artworks as documents in their own right. On this view, artwork references something outside itself as part of a broader system, and exposes how it references. The implications of this perspective are discussed, springing from a historical discussion of document epistemology, research on the information behavior of artists and the philosophy of Nelson Goodman. This discussion provides a framework for conceptualizing artistic information behavior along the entire information chain. Framing art-making in the terms of information science in this way may help arts information professionals assist artists, and it provides grounds for deeper co-understandings between artists and information scientists. Additionally, once information scientists consider art as a document, we can begin to see that even non-artistic documents perhaps never were as "objective" or "factual" as they seemed

Optimal map of the modular structure of complex networks

Modular structure is pervasive in many complex networks of interactions observed in natural, social and technological sciences. Its study sheds light on the relation between the structure and function of complex systems. Generally speaking, modules are islands of highly connected nodes separated by a relatively small number of links. Every module can have contributions of links from any node in the network. The challenge is to disentangle these contributions to understand how the modular structure is built. The main problem is that the analysis of a certain partition into modules involves, in principle, as many data as number of modules times number of nodes. To confront this challenge, here we first define the contribution matrix, the mathematical object containing all the information about the partition of interest, and after, we use a Truncated Singular Value Decomposition to extract the best representation of this matrix in a plane. The analysis of this projection allow us to scrutinize the skeleton of the modular structure, revealing the structure of individual modules and their interrelations.Comment: 21 pages, 10 figure

Are creative cities good places for creative people? notes on the social conditions for cultural production in contemporary economy

Purpose: This paper discusses the social conditions for cultural production in contemporary cities, in the context of a globalized economy, with rising importance of the integration of cognitive, symbolic and emotional elements into tradable products and services. Although the agglomeration dynamics of creative activities in urban contexts and the social or spatial inequalities related to processes of urban reorganization in Post-Fordist societies have been analysed in the last years, the interrelations between these aspects still lack adequate investigation and empirical analysis. Methodology/Approach: By synthetizing diverse theoretical contributions related to different levels and interactions arising from creative activities, their transformations into tradable products (commodification) and some of their spatial implications in the urban context (agglomeration, externalities, identity, place branding and gentrification), the article emphasizes the different benefits obtained by the agents involved in this process, potentially contributing for increasing social conflicts and to a process of cultural homogenization with negative implications on the uniqueness and authenticity of places. Findings: Benefits arising from the externalities generated by the agglomeration of cultural production and creative activities can be framed within the "Common Pool of Resources" approach, suggesting that a more balanced share of the benefits can be obtained by means of participatory processes for city planning and development. Research Limitation/implication:The paper is based on a conceptual approach and further empirical research can be useful in order to test the formulations proposed. Originality/Value of paper: This analysis leads to the identification of different questions for further research, by combining quantitative analysis for the measurement of cultural and creative externalities and modelling processes for the distribution of benefits arising from cultural production, with qualitative analysis related to participatory processes of urban planning and monitoring
