Yet another prezi, from a lecture I gave on citizen journalism and new forms of news dissemination. I discuss digital content dynamics [scarcity/abundance, economy of access], the transition from gatekeeping to gatewatching [Axel Bruns],  analyse Slashdot and Reddit, and use Steven Johnson’s metaphor of Twitter story development as a suspension bridge made of pebbles to illustrate the rising value of aggregation.

Prezi from a lecture examining the influence of information networks on organisations and labour practices. To illustrate both dynamic, I am using notions such as network coordination and transaction costs, Mard Deuze’s notion of liquid labour, Norbert Wiener’s description of the feedback loop, and more importantly John Boyd’s OODA loop as a visualization of the way networks maintain themselves and coordinate the flow of information. The argument of course is that to understand the changes of organisational and labour practices one needs to understand the way networks deal with adversity (coordination and transaction costs); similarly, one has to understand how the length of the feedback loop inevitably leads to decentralization and decision making at the nodal level (Boyd). Crucially, references to sociological favorites such as ‘capitalism’, ‘power’, ‘the social’ are rendered irrelevant.

Prezi from a lecture on utopian narratives of global communication, tracing the roots of cyber-utopianism from the revolutionary influence of the telegraph, to personal computers and the technical architecture of the internet. The telegraph brought the metaphor of communication networks as nervous system, a metaphor also linking the separation of information from carrier to the separation of mind from body. These tropes are still with us more than 150 years later.

Well, the time for leisure, travel, reading, and research is over – back to lectures, tutorials, and endless admin. Below are the slides for my first lecture for this session, tracing an outline of the history of communication networks over the last 150 years. A hasty trip from telegraphy to the internet, with an emphasis on the notion of information networks as a nervous system spanning space.

Prezi from a guest lecture I did on culture jamming – discusses the origins of the practice in the Frankfurt School, examples of jamming techniques, main lines of critique, and examples of co-option of the techniques by corporate branding.

Prezi from a lecture I did on the moral panics surrounding violent video games. The lecture is intended to lead to a discussion on the merits of regulating the supply of and access to games with violent/disturbing content, hence the ambiguity of the position.
