On (not) assembling a market for sustainable energy: heat network infrastructure and British cities

Energy policies increasingly rely on market instruments to meet societal objectives for climate change mitigation. We explore the application of such instruments in low carbon heat markets. Using a conceptual framework derived from actor network theory and economic sociology, we examine the role of technical-economic models as market devices in two heat network proposals in British cities. Government intermediaries relied on the models to enact the mutual financial and carbon benefits of an area-wide heat market, and to enrol multiple public sector organisations in innovation. In practice, the models produced the opposite response: parties synthesised the modelled cost–benefit calculations into the existing public services market agencement and translated the model numbers ino opportunities to secure competitive advantage for their own organisation. These activities undermined the projected cost and carbon saving logic of the collective actor solution. The findings demonstrate the potent economic agency of market-emulating public finance and competitive procurement instruments in governing such organisational decisions, and indicate the limited traction of a low carbon calculus, which lacked significant political or senior management sponsorship. Questions are posed about the formatting of economic agency suited to securing the common goods of a sustainable society.     

A good hustle: the moral economy of market competition in adult webcam modeling

In this article, we examine how models working on Chaturbate, one of the world’s most popular adult webcam platforms, negotiate and make sense of the dynamic ways in which this platform configures their competitive environment. By combining different perspectives from the field of economic sociology, we demonstrate how competition on Chaturbate is shaped by various market devices whose strategic negotiation informs – and is informed by – the moral economy articulated on web forums where models gather to discuss their work experiences and market strategies. We first introduce Chaturbate and the ways in which it organizes market competition, surveying the environment models have to negotiate. We then zoom in on two controversial strategies for beating the competition, each of which upset the moral economy of Chaturbate’s model community. Subsequently, we turn to what models term ‘the hustle,’ which encompasses a number of competitive strategies and criteria judged to be fair and thus legitimate. The final part of our analysis considers the limitations of the hustle, as well as the meritocratic and entrepreneurial discourse that surround it, in light of what we identify as Chaturbate’s ‘manufactured uncertainty.’     

Senses and artifacts in market transactions: the Korean case of agricultural produce auctions

This article examines the relationship between the senses, artifacts, and trade at South Korean agricultural produce auctions. It explores the impacts of market devices on sensory interactions between auctioneers and buyers that are essential to market transactions. Through ethnographic interviews and participant observations at Garak Market, Seoul, this study compares hand signal trading with electronic trading in agricultural produce auctions. It analyzes how the senses affect auction price estimation and formation, as well as their contribution to economic agency and social relationship among economic actors. The study then examines the impact of new market devices in electronic trading (e.g. trading screens, computer monitors, and wireless bidding terminals) on trading’s sensory aspects of seeing or hearing. It argues that the devices change the modality of sensory interactions between auctioneers and buyers. This transforms power struggles, forming a looser but more equal relationship between auctioneers and buyers and decreasing the overall auction price in the market.     

Ethical consumption applications as failed market innovations: exploring consumer (non) acceptance of ‘quasi’ market devices

ABSTRACT

In this paper, I conceptualise ethical consumption applications (ECAs) as market innovations inflected in processes of configuring market actors and market (re)framings. The introduction of ECAs through the work of civil society is not only about changing frames of market exchange, but also work in the register of making ‘good consumers’ and consumers as ‘agents of change’ and moralising markets. Thus, a more accurate concept for these devices is suggested: ‘quasi’ market devices. The main aim of this paper is to analyse how consumers attached to and resisted use of ECAs designed to assist in product choices and shape responsible everyday practices. Based on qualitative fieldwork in Sweden, the article applies a methodology grounded in Science and Technology-inspired market studies in combination with Consumer Culture Theory’s (CCT) interest in identity work and sense-making associated with technology consumption. Although available at the time of the empirical data collection period of the study, all three apps were off the market during the analytic work of this paper; a major argument for focusing on barriers to acceptance of the apps and trying to conceptualise how such non-acceptance can be understood.     

An (in)visible universe of grief: Performative disidentifications with white motherhood in the We are not Trayvon Martin blog

This essay offers a critical rhetorical analysis of social media discourse of white mothers protesting the acquittal of Trayvon Martin’s killer. I argue that through affectively charged performative disidentifications, white mothers contributing to the We are not Trayvon Martin blog worked within and against norms of ideal motherhood to challenge dominant formations of whiteness in ways that exposed the privileged status of U.S. American white motherhood and reconceptualized motherhood as an affective orientation toward antiracism. Unpacking affectively charged performative disidentifications with privileged racial identities is important for enhancing understandings of white antiracist rhetoric and fostering formations of white antiracist consciousness.     

The contribution of urban-scale environmental monitoring to materials diagnostics: A study on the Cathedral of Modena (Italy)

The problem of environmental monitoring aimed at identifying and evaluating the weathering mechanisms affecting historical stoneworks is here discussed and a methodology based on the use of already available, long record, urban-scale environmental data is proposed. An example of its application to the Cathedral of Modena (Italy, XII-XIV century, included in the UNESCO's World Heritage List) is then presented. In this case, the methodology allowed the identification of the main degradation causes, which found significant confirmation by material diagnostics on the available samples and finite element structural modelling. Thanks to the decay causes identification allowed by the proposed methodology, more effective restoration procedures can be outlined.     

Detection of diagenetic alterations by Spectroscopic Analysis on Archaeological Bones from the Necropolis of Poseidonia (Paestum): A case study

Understanding the chemical and physical alteration in archaeological bones, occurred after burial, is very interesting for researchers. In this paper, we present a study on the diagenetic alteration of human archaeological bony tissues from Paestum (South Italy), by combining complementary spectroscopic techniques, such as solid-state nuclear magnetic resonance (NMR), infrared spectroscopy (IR), and X-ray diffraction. In particular, ¹³C nuclear magnetic resonance–cross polarization-magic angle spinning (¹³C NMR CP-MAS) spectroscopy allows to identify and discriminate the adsorbed calcite, that is a diagenetic contaminant, from the structural one of apatite and ¹H NMR-MAS spectroscopy shows how the degradation of organic phase of collagen is related to the time. The NMR data are combined with crystalline index, measured by X-ray diffraction, and with the splitting factor obtained by infrared spectroscopy. Moreover, the evaluation of the relative content of biogenic structural carbonate and of diagenetic fluorine is reported.     

A Mössbauer study of some coloured marbles (cipollino mandolato, rosso antico and fior di pesco): implications on the nature of their colour

⁵⁷Fe Mössbauer spectroscopy permits an explanation of the formation of the iron-bearing species present in three types of coloured marbles, known as cipollino mandolato, rosso antico and fior di pesco. Structural Fe²⁺ and Fe³⁺ located in silicates, together with the remains of weakly ferromagnetic hematite, arise from primary sediments. Fe²⁺ located in carbonates and anti-ferromagnetic hematite are formed by redox processes during marble formation. The relative contents of the iron species in the three types of marbles depend on the composition of the primary sediments and on local conditions during metamorphism. Knowledge of the type and amount of the iron species in marbles may help in the reconstruction of the redox processes, which took place during marble formation. The deviations of the Morin transition of the hematites play the role of genetic indicator because purity, crystallinity and the red hues of hematites in marbles can be related to the environment of formation.
