Tripolye Culture

This paper questions the cycling nature of the unification and diversity of pottery forms through a case study of ceramics of the Western Tripolye culture in the Southern Bug and Dnieper interfluve in modern Ukraine. We identified the cultural cycle representing the transition from more unified ceramic assemblages to more diverse ones, and then back to more unified assemblages. This cultural cycle is disturbed by the increase in the diversity of pottery sets at three of ten subsequent time periods we have analysed. The obtained results are discussed in frames of deterministic explanations and the dynamic behaviour of complex systems.

Abstract. The essential services that support urban living are complex and interdependent, and their disruption in disasters directly affects society. Yet there are few empirical studies to inform our understanding of the vulnerabilities and resilience of complex infrastructure systems in disasters. This research takes a systems thinking approach to explore the dynamic behaviour of a network of essential services, in the presence and absence of volcanic ashfall hazards in Montserrat, West Indies. Adopting a case study methodology and qualitative methods to gather empirical data we centre the study on the healthcare system and its interconnected network of essential services. We identify different types of relationship between sectors and develop a new interdependence classification system for analysis. Relationships are further categorised by hazard condition, for use in extensive risk contexts. During heightened volcanic activity, relationships between systems transform in both number and type: connections increase across the network by 41%, and adapt to increase cooperation and information sharing. Interconnections add capacities to the network, increasing the resilience of prioritised sectors. This in-depth and context-specific approach provides a new methodology for studying the dynamics of infrastructure interdependence in an extensive risk context, and can be adapted for use in other hazard contexts.
