The cybercultural moment and the new media field

This article draws on Pierre Bourdieu’s field theory to understand the regenerative “belief in the new” in new media culture and web history. I begin by noting that discursive constructions of the web as disruptive, open, and participatory have emerged at various points in the medium’s history, and that these discourses are not as neatly tied to economic interests as most new media criticism would suggest. With this in mind, field theory is introduced as a potential framework for understanding this (re)production of a belief in the new as a dynamic of the interplay of cultural and symbolic forms of capital within the new media field. After discussing how Bourdieu’s theory might be applied to new media culture in general terms, I turn to a key moment in the emergence of the new media field—the rise of cybercultural magazines Mondo 2000 and Wired in the early 1990s—to illustrate how Bourdieu’s theory may be adapted in the study of new media history

Slashdot, open news and informated media: exploring the intersection of imagined futures and web publishing technology

"In this essay, my interest is in how imagined media futures are implicated in the work of producing novel web publishing technology. I explore the issue through an account of the emergence of Slashdot, the tech news and discussion site that by 1999 had implemented a number of recommendation features now associated with social media and web 2.0 platforms. Specifically, I aim to understand the connection between the development of Slashdot’s influential content-management system (CMS) - an elaborate publishing infrastructure called “Slash” that allowed editors to choose reader submissions for publication and automatically distributed the work of moderating the comments sections among trusted users - and two distinct visions of a web-enabled transformation of media production.

Rethinking the participatory web: A history of HotWired’s “new publishing paradigm,” 1994–1997

This article critically interrogates key assumptions in popular web discourse by revisiting an early example of web ‘participation.’ Against the claim that Web 2.0 technologies ushered in a new paradigm of participatory media, I turn to the history of HotWired, Wired magazine’s ambitious web-only publication launched in 1994. The case shows how debates about the value of amateur participation vis-à-vis editorial control have long been fundamental to the imagination of the web’s difference from existing media. It also demonstrates how participation may be conceptualized and designed in ways that extend (rather than oppose) 'old media' values like branding and a distinctive editorial voice. In this way, HotWired's history challenges the technology-centric change narrative underlying Web 2.0 in two ways: first, by revealing historical continuity in place of rupture, and, second, showing that 'participation' is not a uniform effect of technology, but rather something constructed within specific social, cultural and economic contexts

A note on bundle gerbes and infinite-dimensionality

Let $(P, Y)$ be a bundle gerbe over a fibre bundle $Y \to M$. We show that if $M$ is simply-connected and the fibres of $Y \to M$ are connected and finite-dimensional then the Dixmier-Douady class of $(P, Y)$ is torsion. This corrects and extends an earlier result of the first author

On the existence of bibundles

We consider the existence of bibundles, in other words locally trivial principal $G$ spaces with commuting left and right $G$ actions. We show that their existence is closely related to the structure of the group \Out(G) of outer automorphisms of $G$. We also develop a classifying theory for bibundles. The theory is developed in full generality for $(H, G)$ bibundles for a crossed-module $(H, G)$ and we show with examples the close links with loop group bundles.Comment: This version accepted to appear in the Proceedings of the London Mathematical Society.

Effect of high and low glycaemic index recovery diets on intramuscular lipid oxidation during aerobic exercise

Intramyocellular lipid (IMCL) and plasma NEFA are important skeletal muscle fuel sources. By raising blood insulin concentrations, carbohydrate ingestion inhibits lypolysis and reduces circulating NEFA. We hypothesised that differences in the postprandial glycaemic and insulin response to carbohydrates (i.e. glycaemic index; GI) could alter NEFA availability and IMCL use during subsequent exercise. Endurance-trained individuals (n 7) cycled for 90 min at 70 % V?O2peak and then consumed either high GI (HGI) or low GI (LGI) meals over the following 12 h. The following day after an overnight fast, the 90 min cycle was repeated. IMCL content of the vastus lateralis was quantified using magnetic resonance spectroscopy before and after exercise. Blood samples were collected at 15 min intervals throughout exercise and analysed for NEFA, glycerol, glucose, insulin, and lactate. Substrate oxidation was calculated from expired air samples. The 90 min cycle resulted in >2-fold greater reduction in IMCL in the HGI trial (3·5 (sem 1·0) mm/kg wet weight) than the LGI trial (1·6 (sem 0·3) mm/kg wet weight, P < 0·05). During exercise, NEFA availability was reduced in the HGI trial compared to the LGI trial (area under curve 2·36 (sem 0·14) mEq/l per h v. 3·14 (sem 0·28) mEq/l per h, P < 0·05 respectively). No other differences were significant. The findings suggest that HGI carbohydrates reduce NEFA availability during exercise and increase reliance on IMCL as a substrate source during moderate intensity exercise
