Large Kombewa flake production in north Oman

In this paper we present the results of surveys carried out in February 2016 along a palaeo‐drainage system near the village of Bisyah. We report first on the geological prospection, which was our main goal, and then present our discovery of the only known localities in north Oman of large Kombewa flake production (>10 cm up to 20 cm). Among the scatter of artefacts, we found cores and large Kombewa flakes with two opposed bulbs of percussion, a technology that had not been known in this region until now. In spite of the local features, the typo‐technological traits of the artefacts suggest that at least part of them resemble in some way the Acheulean techno‐complex, but there are still many questions remaining on the age of these artefacts.     

Fucking geographers! Or the epistemological consequences of neglecting the lusty researcher’s body

This article investigates the dichotomy within research on sexuality between the desiring body of the informant on the one hand and the non-desiring body of the researcher on the other. Despite earlier calls to acknowledge and include the eroticisms of the researcher, accounts where the desiring researcher’s body is a central focus remain exceptions to the rule. The main goal of this intervention is to investigate why the absence of the lusty researcher’s body seems to endure. I will first explore some of the reasons researchers might feel inhibited to self-disclose their desires, to continue with uncovering some of the techniques used to sustain the cover of the asexual, disembodied researcher. Afterwards, I will discuss my own experiences as a (junior) researcher in the field, mainly my own discomfort and embarrassment to be perceived as a desiring woman-researcher, and trace how this has informed my own research trajectory. I conclude by suggesting that writing down our negotiations between the validity of our research versus how much we are willing to self-disclose might be a first step towards an improved inclusion of lust and desire in sex research.     

Sustainable management of metallurgical forest on Mont Lozère (France) during the Early Middle Ages

Mont Lozère, located in the French Massif Central region, provides an exceptional context in which to research the impact that charcoal production and metallurgy had on woodlands, along with the role that these activities played in changing the mountain landscape. This study provides an insight into the land use, forest management methods and metallurgical practices in the area during the Middle Ages (11th to 15th centuries). Medieval charcoal burning platforms, archaeological remains that have often been neglected in the past as a source of historical information, along with nearby smelting sites, were identified, sampled and analysed. In this paper, spatial analyses, radiocarbon dating and anthracological and dendro-anthracological studies have been combined in a unique manner. The results reveal that charcoal burners practiced beech coppicing, where the species and diameter of wood used remained the same over a period of four centuries. It is proposed that this form of metallurgical forest management be considered an early example of a sustainable utilisation of natural resources.     

Faults and fault properties in hydrocarbon flow models

The petroleum industry uses subsurface flow models for two principal purposes: to model the flow of hydrocarbons into traps over geological time, and to simulate the production of hydrocarbon from reservoirs over periods of decades or less. Faults, which are three-dimensional volumes, are approximated in both modelling applications as planar membranes onto which predictions of the most important fault-related flow properties are mapped. Faults in porous clastic reservoirs are generally baffles or barriers to flow and the relevant flow properties are therefore very different to those which are important in conductive fracture flow systems. A critical review and discussion is offered on the work-flows used to predict and model capillary threshold pressure for exploration fault seal analysis and fault transmissibility multipliers for production simulation, and of the data from which the predictions derive. New flow simulation models confirm that failure of intra-reservoir sealing faults can occur during a reservoir depressurization via a water-drive mechanism, but contrary to anecdotal reports, published examples of production-induced seal failure are elusive. Ignoring the three-dimensional structure of fault zones can sometimes have a significant influence on production-related flow, and a series of models illustrating flow associated with relay zones are discussed.     

Crops and weeds: the role of weed functional ecology in the identification of crop husbandry methods

This paper brings together the results of five present-day studies of arable weed ecology, and applies these to the identification of past crop husbandry regimes on the basis of archaeobotanical weed assemblages. The contrasting husbandry regimes covered by the present-day studies include irrigation and dry farming, fallowing and rotation, intensive and extensive cultivation, and autumn and spring sowing. The weed floras associated with these regimes were analysed in terms of the functional ecology of the species represented. These same functional attributes, that distinguished contrasting regimes, were then measured for the weed species found accompanying crop seeds in two archaeobotanical studies, of the Islamic site of Khirbet Faris, S. Jordan and Neolithic sites in central Europe. Analyses using these functional measurements resulted in the identification of irrigation at the former and in the identification of sowing time and intensive cultivation at the latter.     

New radiometric ages for the Fauresmith industry from Kathu Pan,southern Africa: Implications for the Earlier to Middle Stone Age transition

The Fauresmith lithic industry of South Africa has been described as transitional between the Earlier and Middle Stone Age. However, radiometric ages for this industry are inadequate. Here we present a minimum OSL age of 464 ± 47 kyr and a combined U-series–ESR age of 542₋₁₀₇⁺¹⁴⁰ kyr for an in situ Fauresmith assemblage, and three OSL ages for overlying Middle and Later Stone Age strata, from the site of Kathu Pan 1 (Northern Cape Province, South Africa). These ages are discussed in relation to the available lithostratigraphy, faunal and lithic assemblages from this site. The results indicate that the Kathu Pan 1 Fauresmith assemblage predates transitional industries from other parts of Africa e.g. Sangoan, as well as the end of the Acheulean in southern Africa. The presence of blades, in the dated Fauresmith assemblages from Kathu Pan 1 generally considered a feature of modern human behaviour ( McBrearty and Brooks, 2000, The revolution that wasn't: a new interpretation of the origin of modern human behavior, J. Human Evolution 39, 453–563),-provides evidence supporting the position that blade production in southern Africa predated the Middle Stone Age and the advent of modern Homo sapiens.     

Still methodologically becoming: collaboration,feminist politics and ‘Team Ismaili’

This article mobilizes a feminist analytic to examine team research and collaborative knowledge production. We center our encounter with team research – a collectivity we named ‘Team Ismaili’ – and our study with first- and second-generation East African Shia Ismaili Muslim immigrants in Greater Vancouver, Canada. We draw upon feminist politics to highlight the ways in which ‘Team Ismaili’ at once destabilized and unwittingly reproduced normative academic power relations and lines of authority. A ‘backstage tour’, of ‘Team Ismaili’ shows the messiness and momentum of team research and sheds light on how collaborative knowledge production can challenge and reconfirm assumed hierarchies. Even as we are still methodologically becoming, through this discussion we strive to interrupt the prevailing silence on team research in human geography, to prompt more dialogue on collaboration and to foreground the insight garnered through feminist politics.     

Craft Production, Exchange, and Political Power in the Pre-Incaic Andes

This article explores the relationship between craft production, exchange, and power in the pre-Incaic Andes, with a focus on recent archaeological evidence from Chavín, Nasca, Tiwanaku, Wari, and Moche. I argue that craft production and exchange in concert with materialized ideologies played vital roles in the development of political power in the Andes. In later state societies, craft production, exchange, and materialization were critical in maintaining and legitimizing established political power.     

政治地理学中的领域概念辨析

领域是政治地理学的重要概念，但是目前国内对领域的内涵缺乏深入的解读和整理。本文在梳理西方对领域概念的理论探讨的基础上，归纳了理解领域概念的三个主要视角，并基于西方相关理论讨论，提出了领域概念的四个基本属性，即多尺度性、多维性、关系性和生成性。继而，通过对西方领域理论的研究，提出未来中国政治地理学的领域研究应该加强的几个方向。本文对于深化政治地理学领域概念的理解，避免传统认识中的偏见和局限，以及更好地制定领域策略、展开领域研究将起到积极的推动作用。
