Mandibular ramus posterior flexure: a sex indicator in Homo sapiens fossil hominids?

Accurate determination of sex in skeletal human samples is very important in anthropological and demographic studies. Recently, Loth and Henneberg have suggested that a new osteological criterion on the mandible, the mandibular ramus posterior flexure (MRPF) had a high sex discriminating effectiveness. A preliminary test applied to a few hominid mandibles )including Australopithecines, Homo erectus, Neanderthals and Upper palaeolithic hominids) apparently confirmed the high reliability of the MRPF as a sex indicator ‘over time and through palaeospecies’. As the pelvis is commonly considered as providing the most significant criteria that allows the establishment of skeletal sexual dimorphism of adults, the present paper evaluates this mandibular feature on a few additional palaeolithic hominids (i.e. Neanderthals and Early Modern Humans) for whom a gender estimation was known based upon the pelvis. This analysis was conducted on the original material and its results appear in contradiction with those of the previous studies made by Loth and Henneberg. A reconsideration of the visual assessment of MRPF as a sex indicator in Homo sapiens fossil hominids is therefore suggested. Copyright © 2000 John Wiley & Sons, Ltd.     

Diameter of the human internal acoustic meatus and sex determination

We report the results of testing the diameter of the internal opening of the acoustic canal in the petrous part of the temporal bone for sex determination of skeletal remains. The method involves measuring the diameter using a suite of ordinary drills. The method is very simple and has the great advantage of utilising one of the sturdiest bone elements of the human skeleton. The method may be especially useful for the analyses of very fragmented skeletal remains or cremated bones, where the petrous bone may still be readily recognisable. The method was tested using a forensic sample of 113 left petrous bones with known sex. Intra‐ and inter‐observer testing was also performed. We found a statistically significant difference in diameter between males and females (means: males: 3.7 mm; females: 3.4 mm; P < 0.009). However, the low predictive value (70%) for correct sexing using two sectioning points ( < 3.0 mm = female; >3.5 mm = male) was disappointing. No additional accuracy was gained by employing both left and right petrous bones (a bilateral sample of 60 petrous bones was also tested), although left and right side diameter is highly correlated (R = 0.778; P = 0.0001).

Craniofacial trauma in the Prehispanic Canary Islands

The current project is a study of craniofacial trauma in a large sample (n = 896) of Prehispanic Canary Islanders (PCIs). The possible causes and social implications of the trauma found are considered, with reference to archaeological and historical data. Variables include the island, period and ecology, the sex and age of the individuals, the distribution of lesions across the skull (by side and by individual bone) and ante‐mortem tooth loss. The results show a fairly high trauma rate (16%), a low prevalence of peri‐mortem trauma (3.8% of all lesions), higher prevalence of trauma in males than in females (25% vs. 13% of all individuals), more cranial than facial lesions (8.9% vs. 3.5% of all elements) and more lesions on the left side of the skull (6.7% vs. 4.5% of all elements) which suggests that the lesions were sustained through intentional rather than accidental agency. There was no correspondence between trauma prevalence and ecology. The archaeological and historical data support the assertion that the lesions may be the result of skirmishing between groups, using weapons such as slingshots, stones and staves. The presence of edged‐weapon lesions on some individuals suggests that these may have been the victims of contact‐period European groups. Copyright © 2007 John Wiley & Sons, Ltd.     

A brief and improper geography of queerspaces and sexpublics in Austin,Texas

This article offers ethnographic and autoethnographic vignettes from my research on cultures of public sex in Austin, Texas. It also tracks some of the ways my own racialization as a black queer man shaped the research project. My approach, which includes an experimental – ‘reparative’ – textual style, offers several interlocking registers of analysis. I bring together my informants' nostalgic remembrances of public sex in Austin; the legal and media circulation of queer sex in general, and public sex in particular, as specifically ‘public’ problems requiring surveillance, administration, and management; the impacts of HIV/AIDS; and the rise of the Internet as a means to connect. In this way, I not only aim to archive sites of desire and their transformation, but to also archive the everyday and intimate affects that animate, make sense of, and give meaning to queerspaces and sexpublics in Austin as elsewhere. In its eclectic mixes of voices and styles, as well as reality and fiction, my ethnography does not simply describe material geographies (men have sex in parks and hook up online) or linear timelines (first there was public sex and then there was AIDS), rather, gesturing as it does toward a psychic geography of intensities, remembrances, and longings, it tries to conjure an expansive affective archive into brief life.     

Αge‐associated Variation and Sexual Dimorphism in Adult Cranial Morphology: Implications in Anthropological Studies

The current paper explores the impact of age and sex on adult cranial shape and size variation in the documented collections from St Bride's and Spitalfields. The scope is to assess the extent to which it is valid to pool age and sex groups in inter‐population comparisons that use cranial data. For this purpose, age and sex differences in cranial shape and size were explored using multivariate analysis of variance, Discriminant analysis and Mann–Whitney tests. The results suggest a clear change in cranial shape with increasing age; however, this change is not statistically significant. Therefore, it is justifiable to pool different age groups in bioarchaeological analyses. Increasing age also has a minimal impact on cranial size among females, whereas among males, its impact is small but statistically significant. Finally, cranial shape and size are significantly different between males and females, irrespective of their age. This dimorphism can be used for the assessment of sex, although attention should be given to over‐classification problems when using discriminant analysis.

Producing consent: How environmental assessment enabled oil and gas extraction in the Qikiqtani region of Nunavut

There is now an extensive body of academic literature examining how the environmental movement contributed to the colonization of Indigenous peoples and development of capitalism in northern Canada. This paper contributes to these discussions by considering how environmental assessment (EA) helped enable hydrocarbon extraction in the Qikiqtani (Baffin Island) region of Nunavut in the 1970s and 1980s. When exploration activities began to threaten the Inuit harvesting economy, communities protested with letters and petitions. The federal government responded to Inuit resistance by referring proposed exploratory drilling and extraction to its new EA process. While Inuit won significant victories during some assessments of proposed exploratory drilling and extraction, federal EA ultimately helped create the conditions for Inuit to consent to oil extraction. EA helped impose material compromises between Inuit and hydrocarbon industries, including preferential hiring of Inuit, a reduction in the scope of proposed extraction, and the rejection of especially controversial proposals for offshore drilling. These concessions, combined with a collapse in the market for sealskins due to international boycotts, persuaded several Qikiqtani communities to support oil extraction in the 1980s. The ensuing extraction and export of oil from the High Arctic accelerated processes of colonial dispossession and reinforced colonial political dynamics.     

Arctic archaeological sites threatened by climate change: A regional multi-threat assessment of sites in south-west Greenland

Climate change threatens many well-preserved archaeological sites in the Arctic. The paper presents the first Arctic multi-threat assessment focusing on the Nuuk region of Greenland. The results suggest that the majority of the 336 known archaeological sites are already exposed to impacts from microbial degradation, permafrost thaw and vegetation, and that these impacts will increase over the next 80 years. Additional impacts from coastal erosion are only noted at a limited number of sites due to a predominant consolidated and uplifting coast. The applied methods represent an important first step to identify threatened sites and emphasize important data limitations.     

The contentious politics of hydropower dam impact assessments in the Mekong River basin

Since the 1990s, many large hydropower dams have been built in the Mekong River Basin. There has been considerable concern about resettlement and compensation linked to reservoir flooding, as well as the impacts of dams on wild-capture fisheries, riparian livelihoods, and aquatic biodiversity and ecosystems. Anti-dam activists in the Mekong Basin have contested these impacts by claiming that dam impact assessments limit the spatial scale of recognized impact areas in order to reduce both the political backlash against projects and the costs of dam development. In this article, we consider the contentious politics of hydropower dam impact assessments in order to understand how the spatial strategies of anti-dam activists influence the recognized scale of dam impacts. We analyze three of the most contested hydropower projects in the Mekong River Basin: the operational Pak Mun dam in northeastern Thailand, the recently completed Lower Sesan 2 dam in northeastern Cambodia, and the planned Sambor dam on the mainstream Mekong River in Cambodia. We argue that the recognized scale of impacts is in part an outcome of anti-dam activists’ different spatial imaginaries and associated scale frames—along with those of state actors, business interests, and project consultants—that inform activist strategies for mobilizing geographically dispersed people to make claims about dam impacts. Although activists have sometimes challenged the spatial extent of project impact assessments, they have also sometimes inadvertently adopted strategies to contest dams that have reproduced project scale frames favorable to dam proponents.     

Experimental Studies and Vulnerability Assessment of Timber-Arched Lounge Bridges

ABSTRACT

There are many preserved timber-arched lounge bridges in China and some of these bridges are hundreds of years old. The woven arch is the main bearing structure of a timber-arched lounge bridge. Few studies still exist about woven arch mechanical performance, a fact that contributes to the improper repair. This article concerns the structural performance of the woven arch. The results of experimental studies on deformation, stress distribution, force-transferring mechanism, and failure modes were presented. Two woven arch models with and without П-shape braces under symmetrical load and asymmetrical load were investigated. The results indicated that the woven arch had high bearing capacity, especially under symmetrical load. The comparison of experimental results obtained for models with and without brace showed that braces modified the failure mechanism and increased the load carrying capacity and integrity. Based on the failure conditions observed experimentally, limit criteria were defined in order to facilitate vulnerability assessment of timber lounge bridges.     

Measuring the performance of planning: the conformance of Italian landscape planning practices with the European Landscape Convention

The assessment of the performance of planning is debated. The evaluation of the conformance of a given national planning system with a set of principles is similarly received with critical and favourable remarks. A relevant case study consists of the conformance of European landscape planning practice with the principles of the European Landscape Convention (ELC). Italy incorporated in 2004 the principles of the ELC with the Code on Cultural Assets and Landscape (CL), which opened the way for new laws, tools, observatories and atlases. The aim of this article is to demonstrate the usefulness of an assessment exercise concerning the conformance with the ELC of planning practice in Italy. We scrutinize planning systems and tools established by peripheral administrations, according to a qualitative and comparative framework. We refine our analysis by focusing on 10 most recent cases and identifying critical issues in current landscape planning practice. The results are promising and show that landscape planning in Italy is increasingly in line with the ELC.
