A Little Bit of Dirt

An examination of the surface deposit of an Etruscan cup said to have been dug up in Cheshire suggests instead that it had been buried in Italy and brought to England in recent times. The method described here might usefully be employed to assess the provenance of buried artefacts.     

TEFL tourism: the tourist who teaches

ABSTRACT

There is evident lineage between the concepts of teaching English as a foreign language (TEFL) and tourism, represented through evocative marketing material, the commoditisation of the TEFL product, teacher motivations and experiences. Yet, to date there has been little attention paid to this relationship. The amalgamation of the two concepts brings rise to the introduction of the niche form of tourism ‘TEFL tourism’, where the tourist travels outside of their usual environment to teach English as a foreign language and whose role shifts between tourist, educator and educatee at various points in their trip. The TEFL tourism phenomenon is explored through the use of a two-phase research approach employing the qualitative examination of blogs written by TEFL teachers and quantitative surveys. Drawing parallels with associated tourism forms including volunteer, education and philanthropic, it is concluded that TEFL tourism is an entity in its own right, with unique characteristics and motivations presented by TEFL tourists. The use of logistic regression facilitated the analysis of TEFL teacher types, presenting a typology classifying tourists as leisure-minded, philanthropy-minded, career-minded and expatriate-minded. This case-study examination facilitates initial comprehension of the TEFL tourism industry, providing basis for subsequent research to be undertaken to enable enhanced sustainable management of the TEFL industry worldwide.     

SCALING UP,SCALING DOWN: EXPERIMENTS WITH HIGH RESOLUTION COMPUTED TOMOGRAPHY SCANNING OF MICROARTEFACTS

Microartefact analysis remains an uncommon practice in archaeology due to the time‐consuming nature of sample processing and analysis and the difficulty of ensuring reliability, replicability, and consistency in material identification and quantification. Work by Huisman et al. (2014) demonstrated the viability of using micro CT (Computed Tomography) to distinguish different kinds of artifactual materials in midden samples, an approach that can help remove “human error” and to speed up the analytical process. However, micro CT samples are limited in size relative to those that can be analysed via High‐Resolution Computed Tomography (HRCT). In addition, the utility of CT techniques for microartefact analysis in different soil types currently is little explored. We present the results of on‐going experimental work using scanning of “cores” containing different sediment matrices and microartefactual materials. Our results are complementary to those of Huisman et al. (2014), showing that microartefacts, including lithic debris, are readily distinguished from enclosing matrices via density class and morphological analysis.     

The survival of PCR-amplifiable DNA in cow leather

We have investigated the survival of PCR-amplifiable mitochondrial and nuclear DNA in a small number of modern and medieval bovine leather samples. The results of this preliminary investigation demonstrate that, while no nuclear DNA can be PCR-amplified from any of the specimens, mitochondrial DNA can be amplified from all samples. To investigate this contrasting pattern of DNA survival further, we have vegetable-tanned cow skin in our own laboratory, and directly assayed the survival of PCR-amplifiable mitochondrial and nuclear DNA at each step of the process. The results indicate that nuclear DNA is reduced to sub-amplifiable levels as a result of the tanning baths, whereas amplifiable mitochondrial DNA survives the complete process. Our results suggest that old and archaeological bovine leather may represent a useful source of genetic information, although this information will most likely be limited to that which can be gained from mitochondrial DNA.     

Late Holocene Historical Ecology: The Timing of Vertebrate Extirpation on Crooked Island,Commonwealth of The Bahamas

We report eight new accelerator-mass spectrometer (AMS) radiocarbon (¹⁴C) dates performed directly on individual bones of extirpated species from Crooked Island, The Bahamas. Three dates from the hutia (Geocapromys ingrahami), recovered from a culturally derived bone assemblage in McKay's Bluff Cave (site CR-5), all broadly overlap from AD 1450 to 1620, which encompasses the time of first European contact with the Lucayan on Crooked Island (AD 1492). Marine fish and hutia dominate the bone assemblage at McKay's Bluff Cave, shedding light on vertebrate consumption by the Lucayans just before their demise. A fourth AMS ¹⁴C date on a hutia bone, from a non-cultural surface context in Crossbed Cave (site CR-25), is similar (AD 1465 to 1645) to those from McKay's Bluff Cave. From Pittstown Landing (site CR-14), an open coastal archaeological site, a femur of the Cuban crocodile (Crocodylus rhombifer) yielded an AMS ¹⁴C date of AD ～1050–1250, which is early in the Lucayan cultural sequence. From a humerus in a non-cultural surface context in 1702 Cave (site CR-26), we document survival of the Cuban crocodile on Crooked Island until AD ～1300–1400, which is several hundred years later than the well-documented extinction of Cuban crocodiles on Abaco in the northern Bahamas. We lack a clear explanation of why Cuban crocodiles likely survived longer on Crooked Island than on a larger Bahamian island such as Abaco. One AMS ¹⁴C date on Crooked Island's extinct, undescribed species of tortoise (Chelonoidis sp.) from 1702 Cave is BC 790 to 540 (2740 to 2490 cal BP), which is ～1500–1700 years prior to human arrival. A second AMS ¹⁴C date, on a fibula of this tortoise from McKay's Bluff Cave, is AD 1025 to 1165, thereby demonstrating survival of this extinct species into the period of human occupation.     

A Neolithic Voyage

Examination of stone artefacts from Maiden Castle, Dorset, led to the identification of a Neolithic saddle-quern which originated in central Normandy. While stone axes from Brittany and jadeitite axes from the Alps have long been known from central southern England, the quern is the largest and heaviest Neolithic import yet identified. It has a bearing on the debate about indigenous or immigrant origins for the Neolithic, but also re-opens the question of the type of boat that plied the Channel at this early period. It is argued that logboats, for which there is evidence, should not be overlooked in favour of skin-boats for which there is none.

Cheating on climate change? Australia's challenge to global warming norms

The international governance of climate change was initially informed by two norms concerning who should take responsibility for mitigating climate change and how such mitigation should be pursued.1 1. These normative debates have also been analysed by Matthew J. Hoffman and Loren Cass (see Hoffman 2005; Cass 2006). View all notes Since the early 1990s, these norms have been contested by several states. In this article the author argues that such contestation is a product of the perceived incongruence between these norms and the domestic conditions of those states they seek to govern. Following an overview of the emergence and contestation of climate governance norms, the author elaborates on this relationship between international norms and domestic conditions. These theoretical assumptions are then explored in the context of Australia's response to international climate governance norms from the late 1980s to 2007. As the author demonstrates, the perceived incongruence of these norms with domestic conditions led Australia's foreign policy makers to contest the norms and focus on the construction of alternative governance processes by reframing the issue of climate change. Through a diversion of attention away from historical emissions to future emissions and possible technological mitigation options, climate governance was temporarily reconciled with Australia's domestic conditions. However, the author suggests that this came at the expense of international equity and long-term national sustainability.
