The emergence of mobile pastoralism in the Eurasian steppe five thousand years ago marked a unique transformation in human lifeways where, for the first time, people relied almost exclusively on herd animals of sheep, goat, cattle, and horses for sustenance and as symbols. Mobile pastoralism also generated altogether new forms of socio-political organization exceptional to the steppe that ultimately laid the foundation for nomadic states and empires. However, there remain striking gaps in our knowledge of how the pastoralist niche spread and evolved across Eurasia in the past and influenced cultural trajectories that frame the human-herd systems of today. Little is known about the scale of pastoralist movements connected with the initial translocation of domesticated animals, how mobility became embedded in pastoralist life, or how movement contributed to the formation of sophisticated political networks. There is a poor understanding of the character of herd animal husbandry strategies that were central to pastoralist subsistence and how these co-evolved alongside pastoralist dietary intake and ritual use of herd animals. We have a remarkably poor understanding of what pastoralists ate, especially the dietary contribution of dairy products - the quintessential dietary cornerstone food of pastoralist societies. ASIAPAST addresses these gaps through a biomolecular approach that recovers the dietary and mobility histories of pastoralists and their animals recorded in bones, teeth, and pottery. This project pairs these methods to detailed analyses of the economic and symbolic use of herd animals preserved in zooarchaeological archives. These investigations draw from materials obtained from key sites that capture the transition to mobile pastoralism, its intensification, and emergence of trans-regional political structures located across the culturally connected regions of Mongolia, Kazakhstan, Russia, Kyrgyzstan, and Uzbekistan.

BEHAVFRICTIONS will use novel models focussing on information-processing frictions to explain choice patterns described in behavioral economics and psychology. The proposed research will provide microfoundations that are essential for (i) identification of stable preferences, (ii) counterfactual predictions, and (iii) normative conclusions. (i) Agents who face information-processing costs must trade the precision of choice against information costs. Their behavior thus reflects both their stable preferences and the context-dependent procedures that manage their errors stemming from imperfect information processing. In the absence of micro-founded models, the two drivers of the behavior are difficult to disentangle for outside observers. In some pillars of the proposal, the agents follow choice rules that closely resemble logit rules used in structural estimation. This will allow me to reinterpret the structural estimation fits to choice data and to make a distinction between the stable preferences and frictions. (ii) Such a distinction is important in counterfactual policy analysis because the second-best decision procedures that manage the errors in choice are affected by the analysed policy. Incorporation of the information-processing frictions into existing empirical methods will improve our ability to predict effects of the policies. (iii) My preliminary results suggest that when an agent is prone to committing errors, biases--such as overconfidence, confirmatory bias, or perception biases known from prospect theory--arise under second-best strategies. By providing the link between the agent's environment and the second-best distribution of the perception errors, my models will delineate environments in which these biases shield the agents from the most costly mistakes from environments in which the biases turn into maladaptations. The distinction will inform the normative debate on debiasing.

Manuscripts which contain commentary alongside the biblical text are some of the most significant and complicated witnesses to the Greek New Testament. First compiled around the fifth century, the commentaries consist of chains of extracts from earlier writers (catenae). These manuscripts became the main way in which users encountered both the text and the interpretation of the New Testament; revised editions produced in the eleventh and twelfth centuries continued to hold the field until the invention of printing. Recent advances have shown that commentary manuscripts play a much more important role than previously thought in the history of the New Testament. The number of known copies has increased by 20% following a preliminary survey last year which identified 100 additional manuscripts. A recent comprehensive textual analysis of the Catholic Epistles indicated that all witnesses from the third generation onwards (some 72% of the total) could stem from the biblical text of three commentary manuscripts occupying a key place in the textual tradition. Investigation of the catena on Mark has shown that the selection of extracts could offer a new approach to understanding the theology of the compilers and the transmission of the commentaries. The CATENA Project will use digital tools to undertake a fuller examination of Greek New Testament commentary manuscripts than has ever before been possible. This will include an exhaustive survey to establish a complete list of witnesses; a database of extracts to examine their principles of organisation and relationships; and electronic transcriptions to determine their role in the transmission of the biblical text. The results will have a direct impact on editions of the Greek New Testament, providing a new understanding of its text and reception and leading to broader insights into history and culture.

Visual perception is central to how we think and behave. However, there are major unresolved issues in understanding how the human mind draws on experience to perceive the dynamic and variable world. The COLOURMIND project, led by Franklin, will tackle these crucial issues with an ambitious investigation of the impact of the visual environment on colour perception that will provide a new theoretical framework for the field. The project will ask ground-breaking questions: What aspects of colour perception are affected by the visual environment, such that people from different environments perceive colour differently?; What processes enable colour perception to calibrate to visual experience and what is their nature and scope?; Does colour perception ‘tune-in’ to the visual input experienced during infancy? COLOURMIND will adopt a diverse range of innovative methods to address these questions, and will: i.) investigate the colour perception of people immersed in natural non-industrialised environments in some of the remotest parts of the world to identify the extent to which visual environment shapes colour perception; ii.) use innovative neuroimaging methods to identify how the visual cortex changes in response to chromatic experience; iii.) pioneer the use of ‘Altered-Reality' (next generation virtual reality) to elucidate calibrative processes in colour perception; and iv.) conduct carefully controlled experiments with infants to address the role of development. The cutting-edge questions, innovative approaches and theoretical power of the COLOURMIND project will lead to breakthroughs on issues that are fundamental to understanding the complexity of the human mind (e.g., learning, plasticity and inference; perceptual development; cultural relativity), and findings will have practical application. Overall, the ambitious project will push the frontiers of multidisciplinary research on colour perception, and will resonate throughout the cognitive and social sciences.
