I am reading Oliver-Smith, Anthony Theorizing Vulnerability in a Globilized World: A Political Ecological Perspective in Bankoff, Greg, Frerks, Georg & Hilhorst, Dorothea. Eds. Mapping Vulnerability: Disasters, Development & People (London: Earthscan, 2004) at 18. On this page there is an argument following explanation of ideological vulnerability concerning broadening semiotics to the context of politics and the economic. The arguments that Oliver-Smith points to are Gottdiener, M. Post-modern Semiotics: Material Culture and the Forms of Post-modern Life (Oxford, Blackwell, 1995) for a critique of the old school language is everything semiotics and Biersack, Aletta. 'Introduction: From the 'new ecology' to the new ecologies' [1999] American Anthropologist, 101(1): 5-18 for an argument to include the political and economic context of semiotic findings. I need to find these references now for my work on semiotics of the computer "how to press". Although I was reading this book as a follow up to a geography book on reactions to the terrorist attacks in September 2001, I found some ideas to continue my semiotics project. I note that my semiotics project did place the computer "how to press" in the human resources field (a business subfield and thus an economic fact), as a positive, and thus the semiotics scholars I had read in 2003 were already aware of this broader semiotics.
