A Cost-Based Ripley’s <Emphasis Type="Italic">K</Emphasis> Function to Assess Social Strategies in Settlement Patterning

Most quantitative approaches to distributional analysis in archaeology assume a homogeneous study surface that is amenable to easy generalisations. This framework has been widely used to describe settlement processes, disregarding the spatial heterogeneity inherent to geographic reality. In other words, researchers have often assumed that the correlation between the elements of a spatial distribution is a function of the Euclidean distance (i.e. straight line distance) between them. Other archaeological studies have tested alternative measures to Euclidean distances, such as cost-based ones, both to describe optimal routes and to assess spatial autocorrelation in a point pattern. Nevertheless, until now there has been no suitable model to introduce these measures into spatial statistical equations. In order to overcome this obstacle, we approach the implementation problem inversely by embedding the spatial pattern under study into a Euclidean frame of reference based on its cost-distance pairwise matrix. This paper describes the application of this methodology on one of the main tools used by archaeologists to assess settlement patterns: Ripley’s K function. We present two case studies, covering both macroscale and mesoscale, with significant variations in the results depending on the use of the Euclidean or cost-based approach. Data, functions and results have been R-packaged for the sake of reproducibility and reusability, allowing other researchers to build upon our methods.     

Party Ideologies and Regional Inequality: An Analysis of Party Manifestos in Japan

ABSTRACT

Regional inequality within Japan has been a key political issue in Japanese politics throughout the entire postwar period. In this analysis, we examine how Japanese parties have positioned themselves on the question of regional inequality, focusing on how the party system response has been shaped by ideas and ideologies. The article analyses two 15-year periods separated by a quarter of a century (1960–75 and 2000–15) during which regional inequalities became a particularly salient and pressing issue. We compare institutional and socioeconomic contexts, broader governing ideas, and policy responses to this issue by major parties in their election platforms (manifestos). We find that party ideology and broader paradigms continued to shape party responses to regional inequality during both periods.     

Characterization of concrete from Roman buildings for public spectacles in <Emphasis Type="Italic">Emerita Augusta</Emphasis> (Mérida,Spain)

The aim of this work is to characterize the original concrete from Roman buildings for public spectacles, theatre and amphitheatre, from Emerita Augusta, Mérida, Spain. An advanced knowledge of the Roman concrete composition is required for a reliable restoration and preservation of these ancient monuments. The concrete was studied through mineralogical (optical polarized microscopy and X-ray diffraction) and petrophysical (bulk and real density, open porosity to water and Hg, mechanical strength and ultrasonic velocity) analyses. With this work, it is possible to fill the gap that exists in this field and the characterization of the materials used in the Roman concrete from these two buildings, never previously studied, despite the significance of this archaeological ensemble, declared a World Heritage Site by UNESCO in 1993. The results allowed us to determine the composition of the Roman concrete and to infer the provenance of the aggregates used in these monuments.     

‘A Bed of Procrustes’: The Aden Protectorate and the Forward Policy 1934–44

This article explores attempts by British colonial officials based in Aden to extend systems of political administration to the colony's tribal hinterland during the late interwar and early wartime period. Commencing initially with delicate attempts to recast faltering relations between tribal chiefs and their subjects, the policy would culminate a decade later with the despatch of British military units throughout the furthest extents of the protectorate in support of a range of direct political agreements with local rulers that would eventually set the conditions for federation. The intervening years featured a series of little-known debates among various officials on how precisely to cement British influence in the tribal areas, and the philosophy of administration to be pursued to that end. These would expose an element of confusion as to which techniques would best satisfy British policy, and reveal a preference on the part of some for the application of methods atypical of those used elsewhere under Colonial Office jurisdiction, and which drew their inspiration instead from systems of control used on India's volatile frontiers.     

The Supply of Glass at Portus Ilicitanus (Alicante,Spain): A Meta‐Analysis of HIMT Glasses

Portus Ilicitanus (Picola, Alicante) was the main sea harbour of the Roman Colonia Iulia Ilici Augusta and as such played a crucial role in the supply of fundamental commodities to the Iberian Peninsula. Excavations yielded large quantities of glass in fourth‐ and early fifth‐century contexts. Elemental analysis of 60 samples by laser ablation – inductively coupled plasma – mass spectrometry (LA–ICP–MS) confirmed that the glasses were imported from the Eastern Mediterranean. A majority of the glasses correspond to the HIMTa primary production group, which originates from Egypt. The statistical evaluation of published data of 589 HIMT glasses further revealed differential distribution patterns of the HIMTa and HIMTb subtypes between the Eastern and Western Mediterranean, suggesting chronological trends that are linked to wider geopolitical changes. This demonstrates the need for systematic large‐scale approaches to identify supply patterns and possible factors underlying geographical differences and/or chronological developments.     

A Zoroastrian Dispute in the Caliph’s Court: The Gizistag Abāliš in its Early Islamic Context

The Gizistag Abāli? is a ninth- or tenth-century Pahlavi text, recording a debate which took place at the court of al-Ma?mūn between a Zoroastrian priest and a heretical dualist. This article, the first in-depth study of this important work, examines the text in its broader Islamicate environment. It argues that the narrative itself is probably fictional, but reflects a real historical phenomenon, namely the interreligious debates which took place among Zoroastrians, Muslims, Christians, and Jews during the ?Abbasid period. It argues that the text is a unique Zoroastrian example of a literary genre that was common among Christians at the time, namely, “the monk in the emir’s majlis.” By comparing the Gizistag Abāli? to these Christian texts, it explores why Zoroastrians generally did not launch explicit polemics against Islam, comparable to those of other non-Muslim communities. It seems that Zoroastrian authors were more concerned with explaining their own doctrines than critiquing the beliefs of others. This is curious considering the large numbers of Zoroastrians who were converting to Islam at the time. Finally, the article proposes new ways of refining the way we read Pahlavi texts, by analyzing them alongside the literatures of other religious communities in the early Islamic empire.
