This chapter will focus on the deep evolutionary history of the cognitive capacities underlying linguistic iconicity. The complex capacity for linguistic iconicity has roots in a more general cross-modal ability present throughout the animal kingdom, cross-modal transfer. Cross-modal transfer is the ability to make basic inferences about sensory properties of an object in multiple modalities based on experience from only one. This situates iconicity as a fundamentally cross-modal phenomenon; part of a broader, uniquely human cross-modal cognitive suite which includes relatively rare phenomena like synesthesia, alongside more ubiquitous phenomena like sensory metaphor and cross-modal correspondences. Evidence suggests the evolutionarily deep capacity for cross-modal transfer was honed into more sophisticated capacities underlying iconicity by an evolutionary ratchet of increased prosociality during human self-domestication. This period provided strong selective pressures for increasingly complex cross-sensory communication, and eventually, the predominantly arbitrary symbolic systems that underpin modern human language. This is a peer-reviewed preprint of the work below.Cuskley, Christine and Kees Sommer (forthcoming). The evolution of linguistic iconicity and the cross-modal cognitive suite.

Turbine blade cooling has been a topic of significant interest, as increasing turbine entry temperatures result in higher cooling requirements. The present numerical method divides the blade into a finite number of elements in the span and peripheral directions and solves the heat transfer fundamental equations for convection and conduction in both directions. As inputs, the span and chord gas temperature and heat transfer coefficient distributions are required. The results include high resolution temperature prediction for the blade and coolant, at all span and chord positions. The advantages of the method include the capturing of blade temperature variation in all directions, while considering the thermal diffusion due to conduction. Mach number effects to the resulted blade and coolant temperature are highlighted, as local distribution of the gas static temperature can have a dominant role. The effect of averaging the input parameters to the predicted blade temperature is discussed and finally, different values for the material conductivity are simulated and the results are analysed.

This book is a journey through coexisting, emerging or speculated about, types of digital value transfer infrastructures. Using digital value transfer infrastructures as a central case study, this thesis is concerned with unpacking the negotiation processes that shape the governance, design and political purposes of digital infrastructures that are closely linked to the public interest and state sovereignty. In particular, the papers that are assembled in this manuscript identify and inspect three main socio-technical developments occurring in the domain of value transfer technologies: a) the privatization and platformization of digital payment infrastructures; b) the spread of blockchain-based digital value transfer infrastructures; c) the construction of digital value transfer infrastructures as public utilities, from the part of public institutions or organizations. Concerned with the relationship between law, discourse and technological development, the thesis explores four transversal issues that strike differences and peculiarities of these three scenarios: i) privacy; ii) the synergy and mutual influence of legal change and technological development in the construction of digital infrastructures; iii) the role of socio-technical imaginaries in policy-making concerned with digital infrastructures; iv) the geography and scale of digital infrastructures. The analyses lead to the argument that, in the co-development of legal systems and digital infrastructures that are core to public life, conflicts are productive. Negotiations, ruptures and exceptions are constitutive of the unending process of mutual reinforcement, and mutual containment, in which a plurality of agencies – expressed through legal institutions, symbolic systems, as well as information and media structures – are entangled.
