Marine Data,Access, and Interoperability: Two Case Studies of English National Records

Abstract

The aim of this paper is to discuss the long-term management of marine historic environment archives, focusing on the comparison of English Heritage’s National Record of the Historic Environment (NRHE) with the United Kingdom Hydrographic Office (UKHO) as case studies.

Within marine (and terrestrial) contexts, archaeological archives are unique records of survey, excavation, and associated research of the historic environment. They are a resource which allows understanding of the human past to be developed, reviewed, and reinterpreted as new data is gathered. As such, they are significant for research, development-led studies, education, outreach, and public enjoyment. At a time when there is a significant focus on data from the marine environment, both within the UK and more widely across Europe, this paper puts forward some initial recommendations to enable further interoperability between these two key national datasets.

Analysis of these datasets highlighted some interesting points, including the quantification and qualification of the scale of discrepancies between data providers (NRHE and UKHO), and how these can be overcome to allow comprehensive, reliable, and accessible data on which to base long-term planning, decision-making, and resource management. This will ensure a consistent approach, enabling the successful long-term management of historic environment archives, and making historic environment data readily accessible to the wider public.     

Management of Historic Shipwrecks Through a Combination of Significance and Conservation Assessments

Abstract

Corrosion modelling of decay rates of the iron wrecks in Port Phillip Bay, Victoria, has enabled an estimation of the speed at which the historic resource of iron shipwrecks is disappearing. Use of the significance ranking of the iron wrecks, based on the Australian National Standards for significance assessment, provides a useful guide to decision-making, but decisions based solely on these criteria can lead to less than optimal results. From the corrosion rates and the amount of residual metal thickness in structural elements it is possible to determine a conservation ranking that is based on the need for intervention and the chances of being successful in stabilizing the wrecks. The arithmetic product of the significance and conservation rankings defines the treatment score or ranking which forms the basis for rational decision making about deployment of resources.     

Gramsci's unorthodox Marxism: political ambiguity and sociological relevance

Gramsci's work continues to enjoy popularity amongst academics and activists. There is nonetheless a real question about the relevance of his central political ideas for the twenty-first century. This paper defends the thesis that Gramsci's humanism is part of a long tradition of political thought which dates back to Machiavelli, and that although this national-popular humanism is now outdated for reasons which are suggested in the writings and films of Pier Paolo Pasolini, there is also a sociological component to Gramsci's theorising that retains resonance today.     

Rib fractures in the archaeological record: a useful source of sociocultural information?

Investigation of palaeopathological fractures has been shown to provide important information on past societies. However, despite the fact that rib fractures are amongst the most commonly recorded types of fractures in archaeological bone, little attention has been paid to them. Although there will be sites with badly preserved ribs, making their study difficult, this will not always be the case. Recent clinical investigations have highlighted the potential significance of rib fractures with regard to morbidity and mortality, and their importance in relation to health is now appreciated. This study investigates rib fractures in 352 adults from St. Martin's churchyard, Birmingham, England. The crude prevalence of rib fractures was found to be 15.6% and the true prevalence rate 2.3%. The majority of the fractures occurred in males, and those buried in vaults were less likely to have a fracture than individuals from earth‐cut graves. In 11 individuals the fractures were healing at the time of death, and in these cases death was probably related to one of the complications that are frequently linked to fractured ribs. Certain types of accidents may have been linked to these more serious fractures, as 70% occurred in the same anatomical area. Other rib fractures were associated with pathological conditions, such as osteomalacia and osteoporosis. Overall, the study of the rib fractures in this collection provided valuable information that aided interpretation of the lifeways of individuals investigated. It is argued that where preservation permits, studies of fractures in archaeological bone should include ribs. Copyright © 2005 John Wiley & Sons, Ltd.     

历史文化村镇旅游流季节性特征比较研究——以西递、周庄为例

本文以西递和周庄为例,对历史文化村镇旅游流季节性特征进行比较。研究表明,两地在旅游流季节分布不均匀性、季节分布模式和季节划分方面均存在一定差异。对基尼系数和季节性强度指数的分析表明,两者在描述旅游流的季节性变动特征方面具有可替代性,且前者在一定程度上优于后者。另外,旅游地发展阶段也会对旅游流季节性特征有一定影响。论文建议旅游流季节性特征可作为旅游地发展阶段的一项评估指标。     

Description,significance and frequency of the acetabular crease of the hip bone

The acetabular crease is a linear indentation located in the antero‐superior quadrant of the surface of the acetabulum at the level of the Byers Feature 17. Considered by palaeoanthropologists as a discrete trait, it has received scarce attention and the mechanisms underlying its formation and variations according to sex and age remain largely unclear. The purpose of this study, carried out on a large sample from a historic population in France, was to (i) analyse variations according to side, sex and estimated age at death; (ii) assess diachronic variations; and (iii) compare prevalence in various prehistoric and historic populations. Hip bones from a total of 425 subjects of both sexes and all ages were studied. Specimens were from two French historic samples dating from the 11th to 13th centuries and 16th to 17th centuries. The proportion of subjects that died young was higher in the 11th to 13th century group, but the prevalence of the acetabular crease was comparable between the two groups regardless of site or laterality (unilateral or bilateral). No sexual dimorphism or correlation with age was noted at either period. The acetabular crease appears to be a stable anatomical trait throughout adult life, with no predominant side and no correlation with sex. The significantly higher prevalence of the acetabular crease in some historic French samples and in prehistoric native Canadian populations could be linked to greater biomechanical stress during childhood in rural medieval populations and in the prehistoric period.

A tale of two regions: geopolitics,identities, narratives,and conflict in Kharkiv and the Donbas

In 2014 Russia occupied and then annexed the Ukrainian region of Crimea, and subsequently incited and later directly supported a rebellion in southeastern Ukraine, ostensibly in both cases to protect the Russian-speaking population. Although the Crimean gambit was quickly resolved in Russia’s favor, at least on the ground, the fighting in the Donbas region of eastern Ukraine continues with huge loss of life, well over 2 million internally displaced persons, and massive damage to infrastructure. On the other hand, in the neighboring Kharkiv region, the population remained loyal to the Ukrainian state and Russian incitements to rebellion were rebuffed. This paper delves deeper into the mindset of the residents of eastern Ukraine to ascertain why support for Russia differs between these two regions. It focuses on the identities, memories, and narratives of the main groups of residents inhabiting the Donbas and Kharkiv Oblast. Then it compares the attributes of these main groups to each other to illustrate their differences. It characterizes the geopolitical narratives promoted by Russia to generate support for its actions to re-construct the Russian geostrategic area of control and demonstrates where and with which group these emotive narratives were successful and where and why they failed.     

Seismic performance of historical vaulted adobe constructions: a numerical case study from Yazd,Iran

Past earthquakes have demonstrated that historical vaulted adobe buildings are highly vulnerable to seismic actions. Hence, it is crucial for such building typologies to be evaluated in terms of seismic capacity. To this end, this article deals with the seismic performance of historical vaulted adobe houses from the city of Yazd, Iran as one of the seismically active areas of the world and possessing a very rich adobe heritage. Thus, and based on a detailed geometrical survey, a representative sample of adobe houses from Yazd was studied using a simplified in-plane analysis based on three geometric indexes. Concerning the out-of-plane behavior, a deeper assessment was conducted by performing a numerical study, where the main influential parameters on the seismic behavior of vaulted adobe buildings were considered. The numerical analyses were carried out by adopting the limit analysis theory implemented in the Block2D software. The results obtained indicate the safe in-plane behavior of most of the houses and the safe out-of-plane response of the sample under gravitational loads. However, the sample out-of-plane safety under earthquake-induced loads seems to be a matter of concern.
