Synthesis equivalence of triples

This working paper describes a framework for compositional supervisor synthesis, which is applicable to all discrete event systems modelled as a set of deterministic automata. Compositional synthesis exploits the modular structure of the input model, and therefore works best for models consisting of a large number of small automata. State-space explosion is mitigated by the use of abstraction to simplify individual components, and the property of synthesis equivalence guarantees that the final synthesis result is the same as it would have been for the non-abstracted model. The working paper describes synthesis equivalent abstractions and shows their use in an algorithm to compute supervisors efficiently. The algorithm has been implemented in the DES software tool Supremica and successfully computes modular supervisors, even for systems with more than 1014 reachable states, in less than 30 seconds

Civic Associations That Work: The Contributions of Leadership to Organizational Effectiveness

Why are some civic associations more effective at advancing their public agendas, engaging members, and developing leaders? We introduce a multi-dimensional framework for analyzing the comparative effectiveness of member-based civic associations in terms of public influence, member engagement, and leader development. Theoretical expectations in organization studies, sociology, political science, and industrial relations hold that organizations benefiting from either a favorable environment or abundant resources will be most effective. Using systematic data on the Sierra Clubs 400 local organizations, we assess these factors alongside an alternative approach focusing on the role of leaders, how they work together, and the activities they carry out to build capacity and conduct programs. While we find modest support for the importance of an organizations available resources and external environment, we find strong evidence for each of our three outcomes supporting our claim that effectiveness in civic associations depends to a large degree on internal organizational practices.This publication is Hauser Center Working Paper No. 36.

Innovation dialogue - Being strategic in the face of complexity - Conference report

The Innovation Dialogue on Being Strategic in the Face of Complexity was held in Wageningen on 31 November and 1 December 2009. The event is part of a growing dialogue in the international development sector about the complexities of social, economic and political change. It builds on two previous events hosted the Innovation Dialogue on Navigating Complexity (May 2009) and the Seminar on Institutions, Theories of Change and Capacity Development (December 2008). Over 120 people attended the event coming from a range of Dutch and international development organizations. The event was aimed at bridging practitioner, policy and academic interests. It brought together people working on sustainable business strategies, social entrepreneurship and international development. Leading thinkers and practitioners offered their insights on what it means to "be strategic in complex times". The Dialogue was organized and hosted by the Wageningen UR Centre for Development Innovation working with the Chair Groups of Communication & Innovation Studies, Disaster Studies, Education & Competence Studies and Public Administration & Policy as co; organisers. The theme of the Dialogue aligns closely with Wageningen UR’s interest in linking technological and institutional innovation in ways that enable ‘science for impact’

Good Helping Relationships in Child Welfare: Co-authored Stories of Success (FULL REPORT)

This project involved multiple, in-depth interviews with six worker-client dyads from child welfare. The dyads were selected on the basis of workers and clients agreeing that they had worked through some degree of negative interpersonal process toward the achievement of a good working relationship. For each dyad, two individual interviews with the worker and the client were followed by a joint interview. These interviews produced stories that described from workers\u27 and clients\u27 perspectives how the relationship developed over time, how difficulties were dealt with, and what impact the relationship had on the participants. Although these stories were written by the researchers, they were co-authored by workers and clients in the sense that the participants reviewed drafts of their stories, made suggestions for revisions, and agreed that the final product fairly represented their experience. Across story analyses yielded common themes with regard to worker and client contributions to the development of a good relationship, the qualities of a good relationship, and central issues and turning points in relationship development and client change. The results paint a picture of a good working relationship that is deeply human, integrates personal and professional elements, and takes time and effort to develop. Findings also provide insights about how the challenges of developing good relationships in child welfare, and in any helping endeavour, can be dealt with productively
