Building Anderita Late Roman Coastal Defences and the Construction of the Saxon Shore Fort at Pevensey

The construction of the Roman coastal installation at Pevensey (East Sussex) in the late third century represented a building project of considerable importance, size and complexity. A study of the surviving material has identified the lithologies employed in the fort's construction, the approximate quantities in which they were present and the likely areas from which they were quarried. Local sources were exploited wherever possible, although an insufficient supply of brick seems to have forced the builders to look further afield for a substitute material for use in the bonding courses. The location of the quarries suggests that the majority of raw materials were moved by boat, and that the transport fleet required was remarkably small. Estimates of the length of construction for the later series of Shore Forts range from less than three years to over four decades. The labour and transport requirements have been calculated for Pevensey, allowing a discussion of the feasibility of each of these proposed time scales. It is argued that all were achievable, although in the briefer scenarios the army would have been unable to provide sufficient manpower, necessitating a draft of civilian labourers.     

A multidisciplinary approach to reconstructing Late Glacial and Early Holocene landscapes

Understanding palaeotopographical variability forms the basis for understanding prehistoric societies. Alluvial and lacustrine environments, in particular, are key areas with both a high archaeological and palaeoecological potential. However, the often deep stratification of these sites, the high water table and the complex sedimentological variations can hamper a detailed reconstruction of the spatial relationship between prehistoric settlement and their environment. Combining different remote and proximal sensing techniques and coring data, can offer detailed insight into such landscapes. More specifically, the integration of mobile geophysical methods allows the collection of unprecedented continuous information on large-scale palaeolandscape variability. In this study we present a combined approach in order to map and model prehistoric landscapes and river systems in and around a Late Glacial palaeolake in north-western Belgium. Based on filtered and unfiltered digital elevation models, a survey area of 60 ha was selected, in which detailed mobile multi-receiver electromagnetic induction survey was conducted. The results allowed for the delineation of palaeochannels in the area and enabled modelling the depth of these features in the survey area, providing insight into their flow characteristics. ¹⁴C sampling enabled the dating of the evolving river system to the transition between the Late Glacial and the Early Holocene. Through additional coring, this river system could be traced further through the palaeolake area. Based on these results a detailed reconstruction was made of the palaeotopography that harboured the Final Palaeolithic and Early Mesolithic occupation of the study site.     

Are new patterns of low‐income distribution emerging in Canadian metropolitan areas?

Recent studies on urban poverty in Canadian cities suggest a growing spatial concentration of poor populations within metropolitan regions. This article assesses trends in the intra‐urban distribution of the poor population from 1986 to 2006 in eight of Canada's largest cities. We consider five well‐known dimensions of segregation, as identified by Massey and Denton (1988) , in order to examine changes in the spatial distribution of poor populations within metropolitan areas: evenness, exposure, concentration, clustering, and centralization. These indices were calculated for low‐income populations at the census tract level using data from five Canadian censuses. Although each metropolitan area has distinctive characteristics, we were able to identify some general trends. The results suggest that, in 2006 compared to 1986, low‐income populations lived in more spatially concentrated areas, which were, at the same time, socioeconomically more homogeneous and more dispersed throughout the metropolitan area. In addition, we observed that over the last twenty years areas of poverty have been located, for the most part, in neighbourhoods adjacent to downtown cores. Nevertheless, we found that poverty has mostly increased in suburban areas located outside inner‐city neighbourhoods. Growing socioeconomic homogeneity and dispersion of low income areas in metropolitan areas reveal new spatial patterns of urban poverty distribution. These findings should be cause for concern as social isolation in the most disadvantaged neighbourhoods could affect the life chances and opportunities for the residents of those areas.     

Jerusalem 720-705 BCE. No Flood of Israelite Refugees

ABSTRACT

Beside the use of ???? in the priestly and poetic material of the Hebrew Bible the term appears several times in First Isaiah. While priestly authors used (verb and noun) only in reference to God as elementary part of his revelation, the meaning in Isa 1-10 and 13-23 differs frequently. ???? ap-pears with regard to God, persons and objects. in Isa 6; 8 and 10,5-34 the term names a phenomenon which is equivalent to the Mesopotamian melammu ?arruti. In Isa 5 and 10,1-4 it is used as expression for the visible image of a person or a nation. Finally in Isa 4,2-6 and 11,10-16 it represents mount Zion as place of God's revelation. Insofar the results of the motif critical investigation approves former redaction critical studies. In contrast to this in Isa 13-23 the term has an almost consistent meaning. In Isaiah's words to the nations it is used for the nation's actual condition and qualifies the situation as good or bad.     

Between Desire and Routine: Assembling Environment and Finance in Carbon Markets

Abstract: This article contributes to emerging research on the social construction of carbon markets by focusing on the mobilisation of desire amongst carbon market actors, and on the routinisation of financial practices within such markets. We examine specifically the markets that have emerged around the Clean Development Mechanism. First, we look at the stories market actors tell each other in advertising and at Carbon Expo. Second, we look at the routinisation of carbon finance through the borrowing of ideas and tools from traditional financial markets. We suggest that the former animates the markets while the latter enables the markets to become “normalised” for financiers. We also suggest that the two aspects however also work in tension with each other, and that the character of this tension is one way of understanding the distinctiveness of carbon markets.     

Low regional diversity of late cave bears mitochondrial DNA at the time of Chauvet Aurignacian paintings

The Chauvet-Pont d'Arc and Deux-Ouvertures caves, located along the Ardèche River (France), contain abundant remains of the extinct cave bear (Ursus spelaeus). Because they also display a variety of Palaeolithic anthropogenic evidences, such as the earliest charcoal drawings recorded to date (Chauvet-Pont d'Arc), and delicate engravings (Deux-Ouvertures), they offer the opportunity of studying the interaction between animals and human beings during a key period for Pleistocene species extinctions. We characterized cave bear specimens from these two sites by radiocarbon dating, stable isotopes, and mitochondrial DNA analysis. In Chauvet-Pont d'Arc, we obtained radiocarbon ages that ranged between 29,000 and 37,300 years before present (BP). The Deux-Ouvertures cave bear specimens clustered to the bottom of this time frame, returning radiocarbon ages of 27,440–30,220 years BP. Cave bear nitrogen isotope values were all compatible with a vegetarian diet. Mitochondrial DNA analysis, carried out on a highly variable domain of the control region, evidenced only two cave bear haplotypes, including a new haplotype, and a common one which largely predominated. We detected both haplotypes in Chauvet-Pont d'Arc, but only recorded the predominant one in the Deux-Ouvertures Cave. Our data put forward the surprising observation that cave bears inhabited Ardèche over a short period of time, from about 37,000 to 27,400 years BP. They were notably present during the first (Aurignacian) phase of human intrusions in Chauvet-Pont d'Arc, 30,000–32,000 years BP. This points to the possible competition for cave sites, presumably on a seasonal scale considering the cave bear habit for hibernation. During this time period, the small number of haplotypes is at variance with the extensive genetic diversity reported elsewhere for much more ancient specimens.     

A First Approach to Links between Animals and Life on Board Sailing Vessels (1500–1800)

Long voyages required serious logistics. Onboard meat supplies were analysed from animal remains found in shipwrecks. Here we present a bibliographical synthesis of results obtained from the study of 33 published shipwrecks in order to assess the importance of the presence of animals aboard and to underline questions still unanswered. © 2011 The Author
