Purpose -The purpose of this paper is to analyse the structures of the relationships between actors in the creative industries sector using crowd-funding, and how co-creation is the basis for reaching balanced centricity in the creative industries. Design/methodology/approach -The Many-to-Many Marketing Theory, Service-Dominant Logic and Service Logic are the theoretical bases for explaining how the changing roles of the actors in the creative industries sector have given the crowd a great capacity for deciding in the value-creation process. A qualitative, case-based approach is used, given the complexity of the phenomenon to be analysed. Findings -The findings of the empirical approach have important theoretical and practical implications. On the theoretical side, it analyses the importance of balanced centricity instead of customer centricity as the basis for system stability. Findings also have implications for service managers, as this can be considered an alternative for certain business projects, especially in the creative industries sector, where a growing demand is identified, not only as a method of financing, but also as a strategy for strengthening the bond with customers. Practical implications -The study has implications for practitioners and scholars. With respect to managers, the "balanced centricity in cultural crowd-funding" model constitutes a significant contribution, because it replaces the prominent position which until now has been enjoyed by the consumer, with the overall balance of the system, in other words, with aiming to benefit all agents. This translates into a change in how strategies are understood and applied in organisations, as in every decision organisations will have to keep in mind the implications that their decisions and actions have on the rest of the agents, with the objective of managing to exploit their "strategic potential". Strategic planning actions are identified. Originality/value -This paper is the first to analyse balanced centricity as the basis for system stability in the creative industries. The new tasks of the customer as a selector and financer of projects increase the roles assigned to the co-creation concept and improve the knowledge of Network Theory for the creative industries.

Abstract-Although architecture-based self-adaptation has been widely used, there is still little understanding about the validity and tradeoffs of incorporating it into real-world software-intensive systems which already feature built-in adaptation mechanisms. In this paper, we report on our experience in integrating Rainbow, a platform for architecture-based self-adaptation, and an industrial middleware employed to monitor and manage highly populated networks of devices. Concretely, we reflect on aspects such as the effort required for framework customization and legacy code refactoring, performance improvement, and the impact of architecturebased self-adaptation on system evolution.

The aim of this article is to explore whether the ecosystem approach is required to understand the new service model of crowdfunding. The value proposition approach offers different interpretations for each of the eight levels of value co-creation as seen in the service ecosystem. A qualitative multiple case-study approach is used to analyze the two most representative crowdfunding platforms in Spain, Verkami and Lánzanos, in terms of the amounts of funds provided. This article offers an analysis of specific cases of crowdfunding in the arts and cultural sector through the biggest platforms in Spain. The sampling design could be improved by including the experiences of crowdfunding projects in other countries in the analysis. The findings could assist service managers and practitioners to improve planning of value cocreation through the value propositions approach, with a variety of actors within the service ecosystem. This article is a contribution to the development of service-dominant (SD) logic in relation to FP 7 and FP 10. Managerial contributions include the development of a crowdfunding service ecosystem model for arts managers, which offers not only a method of generating finance or economic value but also opportunities for strengthening bonds with customers and other stakeholders. This article is unique in that it integrates value proposition categories in micro-, meso-, and macrocontexts and analyzes the different kinds of cocreation that exist in the crowdfunding context.
