Contribution to the geology of Failaka Island,Kuwait: Evidence from sedimentological and petrographic data from the NE part of the island

Kuwait–Georgian archaeological work at Failaka Island showed the need for geological study. Analysis of sediments related to drinking water-collecting cisterns was performed on a Late Islamic settlement (NE part of the island) in 2018. Field sedimentological, grain size and XRD analysis of the sediment profiles showed that the shallow (about 1 m deep) cone-shaped wells are dug in the loose, porous, cross-stratified calcareous coarse-grained quartz sandstones. Three upper layers of quartz sandstones in the profile have high infiltration rate and provide a rare yet ideal material for water retention. The fourth dense layer below, composed of very fine sand and silt fraction, tends to hinder water movement and forms a relatively impermeable water-resistant surface. Thus, the distribution patterns of clay content, grain sizes and porosity of the well-hosting sediments are favourable for freshwater infiltration and harvesting. An additional petrographic analysis was conducted on different types of rocks discovered on the archaeological site, used as building material and fragments of stone artifacts to identify their origin. It was established that archaeological building material is of local origin, whereas the source rocks for stone artifacts were imported.     

Circular cities: exploring local government strategies to facilitate a circular economy

ABSTRACT

Cities are growing rapidly, and the systems of production and consumption that support this growth are contributing to the depletion of natural resources and pollution of the environment. The circular economy model offers an alternative to the predominant take-make-dispose economic system. Local municipalities are seen to have the capacity to encourage sustainable development of the built environment. This paper aims to explore the role of strategic planning in facilitating a circular economy in urban settings. In particular, this research asks: How are local governments facilitating circular economy initiatives through strategic planning? What are the opportunities and barriers when applying circular economy principles through local strategic planning? The research approach used for this paper is a comparative case study of two international municipalities: the City of Melbourne, Australia and the City of Malmö, Sweden. Current strategic planning practice was examined with a focus on circular economy themes. The findings reveal that strategic urban planning can translate circular economy objectives into actions within specific urban areas, although barriers still exist to fully integrating the circular economy model.     

Sources of variation in carnivore tooth-mark frequencies in a modern spotted hyena (Crocuta crocuta) den assemblage,Amboseli Park,Kenya

Distributions and frequencies of carnivore tooth-marks on large mammal long-bone fragments are commonly used to infer the timing of hominin and carnivore access to prey resources in archaeofaunal assemblages. The strength of these inferences, however, is limited by a broad and currently inexplicable range of tooth-mark frequencies across experimental and archaeological assemblages. Controlling for this variation first requires that the sources be identified. Several sources of variation are examined here in an analysis of tooth-marked bone recovered from a modern spotted hyena (Crocuta crocuta) den assemblage in Amboseli Park, Kenya. Results indicate that tooth-mark frequencies: (1) depend on fragment size, (2) vary across mammals of different size classes, (3) are highly variable across equivalent portions of different long-bone elements, and (4) on certain long-bone portions are correlated with bone density and can be depressed in archaeological assemblages subjected to density-mediated attrition. Stronger inferences based on tooth-mark frequencies will require that such variation be taken into consideration, and methods for doing so are suggested.     

Biological Homogeneity and Familial Segregation in the Iron Age Population of Alfedena (Abruzzo,Italy), Based on Cranial Discrete Traits Analysis

The Iron Age necropolis of Alfedena has been well-known since the last century. In this study 10 non-continuous traits of the cranial skeleton are examined in a series of 94 adult individuals (54 males and 40 females). The division of the Alfedena necropolis into tomb circles has permitted the investigation of the possible existence of familial segregation. Our analysis has shown us that the individuals inhumated in the different tomb circles have a common genetic substrate probably attributable to the strong endogamy present in this population.     

Conflict in Pre‐Hispanic Northwest Argentina: Implications Arising From Human Bone Trauma Patterns

The time span ranging from ca. 900 to 1450 A.D. in the South‐Central Andes has been traditionally posited as a period of social unrest, political disintegration and large‐scale conflict due to, primarily, environmental causes. However, the osteological record of traumatic injuries in a sample of 223 adult and subadult crania from different areas of Northwest Argentina does not clearly correspond to the expected scenario of pervasive and formalized armed attacks. Cranial trauma prevalence in the sample is low (17.48%), and no statistically significant differences were met between the sexes. No differences were found when comparing trauma prevalence between settlements or regions, suggesting that location or function of the sites may not have influenced in trauma frequencies. This information more comfortably agrees with a scenario of conflict where several sources of violence may have caused the record of traumatic injuries (i.e. raids, ambushes, etc). These results serve to problematize how conflict is expected to be expressed in the archaeological record, especially in osseous human remains, what sources of violence may have generated the traumatic patterns observed and the intensity of conflict in this region in particular and in the pre‐Hispanic Andes in general.

Cut Mark Cluster Geometry and Equifinality in Replicated Early Stone Age Butchery

Early Stone Age cut marks created during tool‐assisted carnivory potentially offer inferences into hominin butchery behaviour and access to complete or defleshed carcasses. Actualistic butchery trials of 16 goat and cow half‐carcasses were completed by an experienced butcher with replicated Oldowan tools to investigate how the geometric organisation of cut mark clusters reflects flake versus core tool use and bulk muscle versus scrap defleshing. A cluster of cut marks is defined as a series of adjacent cut mark striations that occur at an anatomical location and are bounded by unmarked cortical surface. Tool type and butchery action were predicted to differentially mark certain long bone portions and influence cluster attributes. Moulds of 613 cut mark clusters were photographed and measured using ImageJ software (National Institutes of Health, Bethesda, Maryland, USA) for cluster area, cut mark count, median cut mark length and standard deviation of cut mark length and angle. Analysis suggests the following results: (i) cluster attributes are correlated;(ii) changes in cluster geometry are related to increasing cut mark count and length but not tool type or defleshed muscle amount; (iii) large clusters occur on large animals; and (iv) long bone midshaft portions are cut‐marked during both bulk and scrap muscle defleshing. Analysis of 179 cut mark clusters on long bone shafts of sizes 1–4 mammals from three Okote member assemblages at Koobi Fora, Kenya, shows that archaeological clusters have a similar number of marks when compared with experimental clusters but are significantly smaller, have shorter median marks and include less deviation in mark length and angle. Archaeological clusters corroborate that increasing area is positively correlated with cut mark count, median mark length and standard deviation of mark length and angle. A quantitative inferential model that links cut mark cluster geometry to tool type or the amount of muscle defleshed is not supported by these data. Copyright © 2015 John Wiley & Sons, Ltd.     

The Zoutsteeg Three: Three New Cases of African Types of Dental Modification from Saint Martin,Dutch Caribbean

Dental modification was widely practiced in sub‐Saharan Africa as a form of cultural expression, and during the era of the transatlantic slave trade, it was regularly identified in enslaved Africans who were transported to the Americas. Here, we report three new cases of African types of dental modification from the Caribbean island of Saint Martin that were recently encountered during construction activities in the Zoutsteeg area of Philipsburg, the capital of the Dutch half of the island. The artifacts associated with the burials indicate that they date to the late 17^th century, prior to the foundation of the town of Philipsburg in 1735. The dental evidence further suggests that the three individuals were born in Africa, as opposed to the Americas. This could be confirmed by tooth enamel strontium isotope measurements which yielded values that are inconsistent with an origin in the Caribbean but consistent with an origin in Africa. Unfortunately, neither the dental patterns nor the strontium isotope values allow us to determine their specific origins in Africa. However, both the methods used to modify the teeth and the isotope ratios suggest that the ‘Zoutsteeg Three’ originated in different parts of Africa. Copyright © 2012 John Wiley & Sons, Ltd.     

Changing patterns of carnivore modification in a landscape bone assemblage, Amboseli Park, Kenya

This study compares the landscape-scale taphonomic signal of carnivore modification to the surficial bone assemblage in Amboseli Park, Kenya as it was in 1975 and 2002–2004. Change in predator abundances over time provides a means of assessing the taphonomic signal of carnivore-mediated bone consumption and destruction under differing ecological conditions and varying levels of conspecific competition for resources. The landscape assemblage indicates taxonomic variation in the patterning of carnivore modification to ungulates of different size classes as well as within equivalent size classes. Analyses of long bone elements indicate that the differential destruction of limb ends and the strength of the correlation between limb end abundance and bone mineral density provide an indication of the intensity of carnivore modification to a faunal assemblage. The ability to infer levels of carnivore modification based on limb elements can provide faunal analysts with the tools to determine whether the taphonomic signals in the fossil record relate to carnivore modification, hominin transport of appendicular elements, or both.
