Hi all, from my perspective the impact assessment at local level should always start from the livelihood perspective (i.e. considering the social, economical and ecological dimension). Some weeks ago I read a paper which could interest you all, entitled "Can the ubiquitous power of mobile phones be used to improve health outcomes in developing countries? - There is mixed evidence to support the idea that mobile phones are an effective healthcare intervention in developing countries", which was written by W. Kaplan and published by "Globalization and Health" in 2006. Here you can find the link to the paper: [url]http://www.globalizationandhealth.com/content/2/1/9[/url]. Cheers, Simone
