Revision with unchanged content. Using the Canada International Scientific Exchange Program (CISEPO) this book examines whether narrow or broad health-for-peace interventions are more successful. CISEPO builds bridges to peace between Israelis, Jordanians and Palestinians through medical and scientific co-operation. Drawing on medical, philosophical and international relations sources and interviews with key workers this book explores these concepts. Participants defined project level (narrow) endeavours, and broader, program level undertakings such as the establishment of knowledge networks. While frontline workers favoured narrow, time-limited, projects seeing broad, long-term projects as unrealistic, planners espoused the ‘long view’, accepting that programmatic goals take years to attain. The study suggests that the relationship between narrow and broad concepts is not either/or-both are needed simultaneously in differing measure depending on the undertaking. Short-term successes are necessary to sustain long-term goals and to measure and conceptualize success, but long-term goals are essential for ensuring overall direction and philosophy of the NGO.
