Simtech 08 poster submission: digital upheavals: ethnographic studies on digital-DIY activity

This poster describes current work-in-progress on a digital-DIY research project, exploring how people experiencing life-change configure and re-configure their domestic entertainment, information and communication technologies. The project draws upon a number of theoretical concepts from human-computer interaction, the social construction of technology, material culture and design studies to understand the digital-DIY phenomenon and is methodologically rooted in the ethnographic tradition. This poster describes early pilot-study work utilizing Blythe et al’s (2002) ‘Technology Biographies’ method applied to (amongst other pilot studies) the author’s own autoethnographic study of moving home and concludes with a summary of themes and concepts emerging from this early data. The poster presents proposals for future empirical studies of people experiencing life-change

A Robust Folk Theorem for the Prisoners' Dilemma

We prove the folk theorem for the Prisoner's dilemma using strategies that are robust to private monitoring. From this follows a limit folk theorem : when players are patient and monitoring is sufficiently accurate, (but private and possibly independent) any feasible individually rational payoff can be obtained in sequential equilibrium. The strategies used can be implemented by finite (randomizing) automata.
