Custom and habit(us): The meaning of traditions and legends in early medieval western Britain.

This paper discusses some well–known legends and hagiographic stories, and explores the context of their production and consumption. From an examination of Welsh foundation legends and Cornish hagiographical accounts, we focus on the methods by which versions of history were used in the Middle Ages to provide a context for fundamental changes in the way in which society was organised. It is found that, far from abandoning traditional versions of history, accounts of the past were promoted that sought to couch newer territorial notions of organisation within existing constructions of identity and mediations with the past. In an examination of the production and reception of these popular stories, we attempt to relate the legends to the generation of communal identity and memory. Consequently, drawing on Bourdieu's notion of habitus, we argue that pre–existing beliefs and customs were an important part in the development of newer institutional structures. Rather than initiating new practices that had no grounding in any particular past, institutional developments gained social currency by being inherently grounded in existing facets of cultural identity. In essence therefore, changing societal and institutional structures were unintentionally couched in the language and understandings of existing structures, so that in many ways a concept of continuity was at the very heart of actual change.     

Explaining accommodation and resistance to demands for independence referendums in the UK and Spain

This article examines why the UK Government accepted the 2014 Scottish independence referendum while the Spanish Government opposes a similar referendum in Catalonia. Adopting a most similar research design, we argue that the variation is best explained by perceived political opportunities by the two ruling parties. These are embedded in different conceptions of the state and constitutional designs, mostly mononational in Spain and mostly plurinational in the UK but multiple and contested in both cases. In Spain, vote‐seeking calculations incentivise the Popular Party to oppose a referendum, while its mononational conception of the state and the Spanish constitutional design provide a further constraint and a discursive justification for their position. In the UK, David Cameron's accommodating position was based on the view that the Scottish referendum was low risk – as support for independence was minimal – with a high reward: the annihilation of the independence demand. The Conservatives have recently adopted a more restrictive position because seeming political advantage has changed. The findings suggest that independence referendums will continue to be rare events.     

A new Miocene carnivorous marsupial,Barinya kutjamarpensis (Dasyuromorphia), from central Australia

Binfield, P., Archer, M., Hand, S.J., Black, K.H., Myers, T.J., Gillespie, A.K. & Arena, D.A., June 2016. A new Miocene carnivorous marsupial, Barinya kutjamarpensis (Dasyuromorphia), from central Australia. Alcheringa 41, xx–xx. ISSN 0311-5518.

A new dasyuromorphian, Barinya kutjamarpensis sp. nov., is described on the basis of a partial dentary recovered from the Miocene Wipajiri Formation of northern South Australia. Although about the same size as the only other species of this genus, B. wangala from the Miocene faunal assemblages of the Riversleigh World Heritage Area, northwestern Queensland, it has significant differences in morphology including a very reduced talonid on M₄ and proportionately wider molars. Based on the structural differences and the more extensive wear on its teeth, the central Australian species might have consumed harder or more abrasive prey in a more silt-rich environment than its congener, which hunted in the wet early to middle Miocene forests of Riversleigh.

Dealing with Timing and Synchronization in Opportunities for Joint Activity Participation. 公共活动参与机会中实时性与同步性处理

The ability of people to access opportunities offered by the built environment is circumscribed by various sets of space–time constraints, including the requirements to meet other persons at particular times and places to undertake activities together. While models of space–time accessibility recognize that joint activities may constrain the performance of activities in space and time, their specifications do not explicitly acknowledge the opportunities that individuals of a group have for joint activity participation. Therefore, this article focuses on joint activity participation and argues that collective activity decisions are the outcome of a complex process involving various aspects of timing, synchronization, and social hierarchy. The utility‐theoretic model proposed here quantifies the extent to which opportunities can be jointly accessed by a particular group of people within a specific time period. Central to the approach are three key variables: the attractiveness of an opportunity, the time available for activity participation, and the travel time to an activity location. Because of the multiperson character of joint activities, the determination of these variables is subject to individual preferences, privileges, and power differentials within a group. Specific attention is given to how time‐of‐day and synchronization effects influence the opportunities accessible to a group of individuals. The impact of these factors on joint accessibility is illustrated by a real‐world example of an everyday rendezvous scenario. The outcomes of a simulation exercise suggest that time‐of‐day and synchronization effects significantly affect the benefits that can be gained from opportunities for joint activities.     

What Explains the Carcass Field Processing and Transport Decisions of Contemporary Hunter-Gatherers? Measures of Economic Anatomy and Zooarchaeological Skeletal Part Representation

This paper uses rationale derived from central place foraging models to explore the factors that guide the carcass processing and transport decisions of modern hunters. Using data derived from butchering experiments, I test different economic indices that purportedly reflect the field processing and transport decisions of contemporary African Hadza hunter-gatherers. The results show that no single index predicts part processing and transport for the species examined in this analysis. Processing and transport decisions are, however, patterned in ways that are consistent with theoretical predictions. While similar processes likely guide carcass treatment and transport decisions among all hunter-gatherers, different ecological, social, and historical constraints define the range of solutions to problems involving carcass treatment. In this specific example, intertaxonomic differences in carcass size and bone properties constrain how the trade-offs between field processing and transport costs are resolved. I conclude by suggesting ways in which analysts might make use of central place foraging rationale and models to explain variation in skeletal representation and abundances across time and space.

Lower Pecos and Coahuila peyote: new radiocarbon dates

Peyote, a psychoactive cactus native to the Chihuahuan Desert, has been preserved from excavations at only two archaeological sites: Shumla Caves in the Lower Pecos region of southwest Texas and shelter CM-79 near Cuatro Ciénegas in Coahuila, Mexico. We determined three indistinguishable radiocarbon ages of 5160 ± 45, 5200 ± 35, and 5210 ± 35 ¹⁴C years BP, yielding a mean age of 5195 ± 20 ¹⁴C years BP for the three specimens from Shumla Caves. For one of the Cuatro Ciénegas specimens we obtained the first direct radiocarbon date of 835 ± 35 ¹⁴C years BP. This study demonstrates the use of peyote by inhabitants of the Lower Pecos region of the Chihuahuan Desert about 6000 calendar years ago, and confirms its use by inhabitants of the Cuatro Ciénegas region of the Chihuahuan Desert in Late Prehistoric times. The Shumla Caves' specimens are composed of an aggregate of ground peyote mixed with other plant material, i.e., they appear to be manufactured peyote effigies, and are definitely not intact peyote buttons.
