Shifting narrative strategies: How monument advocates change their stories in response to conflict over time

This paper expands the Narrative Policy Framework (NPF) by employing an exploratory case study approach to examine the construction of narratives temporally. A large-N Twitter dataset concerning the Bears Ears and Grand Staircase-Escalante monuments controversy is utilized to examine the question: how does the use of narrative strategies change over time? Through the application of change-point analysis, we determine time points of significant shifts towards use of the devil-angel shift, scope of the conflict, and causal mechanism strategies. Overall, we find that organizations do not vary their use of narrative strategies over the course of a policy conflict but instead demonstrate discrete changes in response to certain policy events. Based on our findings, we conclude with suggestions for refining and expanding NPF hypotheses. Specifically, we recommend a more contextual analysis of shifts in narrative strategy use in response to specific events over time.     

Correcting temporal frequency distributions for taphonomic bias

In this paper, we expand upon a prior study [Surovell, T.A., Brantingham, P.J., 2007. A note on the use of temporal frequency distributions in studies of prehistoric demography. Journal of Archaeological Science 34, 1868–1877.] that explored the problem of taphonomic bias. Taphonomic bias refers to the tendency for younger things to be over-represented relative to older things in the archaeological record due to the operation of destructive processes like erosion and weathering. Using a database of radiocarbon dated volcanic deposits from Bryson, R.U., Bryson, R.A., Ruter, A. [2006. A calibrated radiocarbon database of late Quaternary volcanic eruptions. Earth Discussions 1, 123–124.], we develop an empirical model of taphonomic bias. In contrast to our prior study in which we modeled taphonomic bias as an exponential function wherein the likelihood of site loss remains constant through time, we argue that the probability of site destruction actually decreases with site age. We further demonstrate how this model can be used to correct temporal frequency distributions and extract demographic histories. We illustrate this approach using databases of radiocarbon dates from rockshelter and open-air sites in the Bighorn Basin, Wyoming, USA, and mammoths and humans in Siberia, Russia.     

The history of stones: behavioural inferences and temporal resolution of an archaeological assemblage from the Middle Palaeolithic

Behavioural issues are a main focus of current Palaeolithic research, especially where the archaeological record of archaic hominids is concerned. Often these issues are approached using archaeological assemblages that are palimpsests defined exclusively by stratigraphic criteria. The aim of this paper is to discuss whether such assemblages are adequate for solving behavioural questions. As a case study, we will present the lithic provisioning strategies documented in level L of the Abric Romaní Middle Palaeolithic site. The results of this study suggest that the number of events and/or the amount of time included in the archaeological assemblages could be relevant when explaining the interassemblage variability, given that palimpsests tend to reduce the behavioural variability. If we want to approach the behavioural domain, we need archaeological assemblages of higher temporal resolution, defined through the identification of single activity events.     

Remembering Ancestors: Commemorative Rituals and the Foundation of Historicity

One of the most elaborated responses to the human perception of being‐in‐time (as the essence of historicity) has been the cult of the ancestors. Consequently, the ancestor cult may be considered foundational for historicity. This is the core idea of this article. It is illustrated with Romanian ethnographic data and elaborated with cross‐cultural examples. A few objects used in commemorative rituals—coliva (a special dish), trees and pots—are interpreted according to their symbolic force of enabling people to live temporality not only fragmentarily (past?+?present?+?future), but as a transcendental unity of the temporal continuum. Finally, the functions of history are specified—namely, identity defining, the critical function, and especially (as revealed by the ancestor cult) the function of memorialization.

A probabilistic framework for assessing spatio-temporal point patterns in the archaeological record

The assessment of spatial patterns in archaeology is hampered by a number of constraints, one of the most serious of which is the intrinsic temporal uncertainty associated with most of the archaeological record. Different types of chronological definition or different degrees of temporal knowledge will suggest different kinds of spatial pattern, ultimately obscuring and restricting our interpretation of the background process, especially in cases where we are seeking a diachronic perspective. This paper addresses these problems by adopting both a probabilistic approach and a more standardised framework for diachronic analysis. First, we define the notion of temporal uncertainty and explore its analytical consequences. Second, we consider two methods by which it might be formally quantified, emphasising (a) the advantages of probability-weighted spatial analysis and (b) the comparison of alternative spatio-temporal patterns via Monte-Carlo simulation. Finally, we apply these methods to a case study that considers the distribution of Middle to Late Jomon (ca.5000–3000 BP) pithouses recorded in the Chiba New Town area of Japan.
