Social Space 2012 (Issue Five): Design Thinking, Social Finance, Impactful Advocacy. The 19 articles in Social Space Issue 5, 2012, explore many aspects of the thinking, finance and activities involved in ongoing, non-profit social developments in Singapore and beyond. Interviews with three thoughtful and at times iconoclastic activists in Singapore and Thailand are followed by: three articles on design thinking and design systems based in Denmark, in Singapore and among the beneficiaries of a Singapore NGO; five articles are on social finance experiences worldwide; and five on aspects of financing advocacy and sustainability in charitable and social causes with a final exploration of today's civil society trends in Singapore.
