Theorising and analysing digital labour: from global value chains to modes of production

This paper considers the following question—where do computers, laptops and mobile phones come from and who produced them? Specific cases of digital labour are examined—the extraction of minerals in African mines under slave-like conditions; ICT manufacturing and assemblage in China (Foxconn); software engineering in India; call centre service work; software engineering at Google within Silicon Valley; and the digital labour of internet prosumers/users. Empirical data and empirical studies concerning these cases are systematically analysed and theoretically interpreted. The theoretical interpretations are grounded in Marxist political economy. The term ‘global value chain’ is criticised in favour of a complex and multidimensional understanding of Marx’s ‘mode of production’ for the purposes of conceptualizing digital labour. This kind of labour is transnational and involves various modes of production, relations of production and organisational forms (in the context of the productive forces). There is a complex global division of digital labour that connects and articulates various forms of productive forces, exploitation, modes of production, and variations within the dominant capitalist mode of production.

The world without outside

The world is all that there is. In the world, ontology and epistemology coincide. The thing and the perspective are part of it, scale is ingested in its multiplicity, communication stops at the world's edge. By reading together Deleuze and Guattari's plane of immanence and Niklas Luhmann's proto-global concept of Weltgesellschaft (“world society”), I suggest a conceptualisation of the world as the materiality of the multiple spaces of creation in an insular, all-inclusive immanence. Deprived of an outside, the world pushes its own understanding of circumference through, first, the expansion of its own limits through the process of worlding, and, second, the multiplication of modes of material (self-)production through its process of othering. Thus, the world swells up from the inside and expands on both the material and the semantic level, producing a multiplicity of fractal microcosms. Issues of responsibility and justice arise that are intricately linked to the materiality of the world and take place in and between the various bodies and spaces of the world but without an overarching hierarchy or principle. This approach is a way of counteracting the all-pervasive Hegelian understanding of synthesis, arguing instead for a plenitude that brims with positivity and that can never become fully complete. The world remains its own infinite process of worlding.

Reduced-Reference Image Quality Assessment Based on Edge Preservation

Assessing the subjective quality of processed images through an objective quality metric is a key issue in multimedia processing and transmission. In some scenarios, it is also important to evaluate the quality of the received images with minimal reference to the transmitted ones. For instance, for closed-loop optimisation of image and video transmission, the quality measure can be evaluated at the receiver and provided as feedback information to the system controller. The original images - prior to compression and transmission - are not usually available at the receiver side, and it is important to rely at the receiver side on an objective quality metric that does not need reference or needs minimal reference to the original images. The observation that the human eye is very sensitive to edge and contour information of an image underpins the proposal of our reduced reference (RR) quality metric, which compares edge information between the distorted and the original image. Results highlight that the metric correlates well with subjective observations, also in comparison with commonly used full-reference metrics and with a state-of-the-art reduced reference metric. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.
