Heritage Monitoring Scouts: Engaging the Public to Monitor Sites at Risk Across Florida

ABSTRACT

Along Florida’s nearly 13,000 km of shoreline, nearly 4000 archaeological sites and over 600 recorded historic cemeteries are at risk from climate change impacts including coastal erosion and a 2-metre rise in sea level. In 2016, the Florida Public Archaeology Network (FPAN) created the Heritage Monitoring Scouts (HMS Florida) programme to engage the public in monitoring sites at risk. The programme grew quickly during the first year of operation to include 233 volunteers who submitted 312 monitoring forms. The programme exists beyond the singular act of a volunteer reporting site conditions; across Florida, varied combinations of local partnerships present unique opportunities for programmes, for example, the pilot program at the Guana Tolomato Matanzas National Estuarine Research Reserve. Preliminary outcomes from the first year of HMS Florida and the pilot indicate the programme is effective in public engagement and a powerful management tool for tracking change to sites over time.     

Biomechanics of coaching maximal instep soccer kick for practitioners

Kicking in soccer has been the subject of scientific research for more than 40 years yet review articles summarizing the biomechanical fundamentals of kick optimization as a guide to coaching are scarcely to be found. The current review article aims to bridge the gap between scientific research into the maximal instep kick (including studies employing 3D motion capture and full-body biomechanical modelling) and the application of such research in coaching. It does so by supplying a scientifically founded, coaching-friendly article explaining identifiable characteristics and motor control sequencing that define this skill. Relevant biomechanical factors are identified in a way that should help coaches better develop training programmes and, at the same time, foster better understanding of the skill among athletes. Such information will contribute to both accelerated skill acquisition and, by concomitant gains in skill efficiency, the development of programmes that minimize risk of injury to athletes during training.     

‘Mucho malo for fascisti’: Languages and Transnational Soldiers in the Spanish Civil War

This article explores the linguistic experiences of transnational soldiers, using the Spanish Civil War as a case study. It argues that communication difficulties provoked by linguistic diversity within the Republican war effort and particularly within the International Brigades, caused the high command to move from a utopian, internationalist policy to a more pragmatic approach. The article evaluates the role played by language intermediaries in this evolving policy and in the wider Republican war effort. Finally, it argues that soldiers grassroots experiences of language contact forged new linguistic forms which underlined a strong sense of shared purpose and identity.     

华沙渠道与中美关系解冻:华盛顿决策内幕

在冷战的国际大背景下,尼克松政府对苏实施的“缓和”战略使得华盛顿打出“中国牌”,致力于改善同北京的关系。而1969年3月中苏边界武装冲突则为美提供了一个契机。在寻求同中国对话的渠道上,华盛顿首先想到的是华沙渠道,即第135次和136次中美大使级会谈,并为此做了充分的准备。尽管史实证明:华沙渠道的进展不像华盛顿期望的那样顺利,但基本上完成了预期的任务:表达了改善对华关系的愿望,并阐明了不会同苏联合作主宰东亚事务的立场。在华沙渠道完成了既定任务之后,华盛顿又将同北京的联络转为巴基斯坦渠道。     

Metrical discrimination between mandibular first and second molars in domestic cattle

The difficulty of distinguishing between loose first and second mandibular molars of domestic cattle (BOS taurus) from archaeological sites is well known. This paper proposes cervical length as a discriminatory measurement. The possibility that cervical measurements of first and second mandibular molars may be sexually dimorphic is also explored.     

The conundrum of castration in the archaeological record: An interpretation of Roman cattle horn-cores from Chelmsford,Essex

Current methods of sexing archaeological cattle bones, in particular the metapodials, are based upon past research into contemporary breeds and this work embraces a limited sample size, spread across a vast geographical area. Although the separation of cows and bulls is not in question, there appears a great deal of subjectivity in the literature concerning the identification of castrated beasts. Living bone is in a dynamic state of equilibrium with the rest of the body and responds to increased loading, that is, an increase in weight of the beast or stress/strain through strenuous movement, by remodelling. If cows and oxen are performing the same work, as for example in ploughing, then loading on the bones will be similar. These bones will thus respond by remodelling in corresponding fashion, and hence any morphological and metrical distinctions will be clouded. Horn-cores are less subject to these constraints, although in some cultures there may be loading on these bones, for example through attaching the harness to the horns for ploughing. The Chelmsford cattle horn-cores constitute waste from some industrial activity and it is argued in the text that horn-working is the most likely candidate, together with possibly tanning. Sexing of the bones strongly indicated male animals, with few females being present. A procedure for detecting castrated cattle (oxen) is presented, the results of which suggest an equivalent ratio of oxen to bulls.     

Archaeozoological research on vertebrates in Central Europe with special reference to the medieval period

This paper is the outcome of a lecture held at the Institute of Archaeology, University College London. It provides a summary in English of the archaeozoological research work which has been carried out in Central Europe during the last 30 years, with special reference to material from medieval times. It is shown that a thorough zoological analysis of bones from excavations provides much information for historical interpretation. Not only was the ratio of wild and domestic animals or of the different species of interest, but also the age and sex structure of the population by taking the function of the site into consideration. Some observations on animal teeth gave indications of distinctive handicrafts. Cut marks on cervical vertebrae of horse skeletons found as grave goods from early medieval times were considered in connection with beliefs and juridical conceptions of that time.     

Identification of the Archaeological ‘Invisible Elderly’: An Approach Illustrated with an Anglo‐Saxon Example

The aim of this paper is to present a method to facilitate age‐at‐death estimation of older individuals (generally those aged 50+ years) in a representative cemetery sample. The purpose of disaggregating catch‐all categories, such as 50+ years, is to enable the exploration of the elderly (those in their 50s, 60s, 70s or 80s) in the context of mortuary archaeology, bioarchaeology and/or palaeopathology. The methodological steps include the following: (1) assessment of occlusal tooth wear in an Anglo‐Saxon cemetery sample from Worthy Park, UK; (2) seriation of the sample, from youngest to oldest, based on the degree of tooth wear; (3) selection of an ethnographically derived model (known mortality profile) by which seriated individuals in the Worthy Park sample could be reallocated to more realistic or appropriate age classes; (4) reallocation of individuals in the seriated Worthy Park sample to the model age classes. A Hadza, Tanzania, hunter‐gatherer profile was chosen to model the Worthy Park sample, although others are available. By using this model, some 66% of the entire adult sample, originally allocated to the single final age category of 45+ years, was distributed across four new age categories from the mid‐40s to mid‐70s. Relatively straightforward, this approach provides a way to identify those individuals, 50+ years old, not normally sensitive to traditional age‐at‐death estimation methodologies currently available.
