Goldsmithing traditions and innovations in colonial Colombia: an analytical study of crucibles from Santa Cruz de Mompox

SUMMARY: The 16th-century Spanish conquest of Colombia brought new technologies that altered and interacted with native metalworking traditions. In the colonial village of Santa Cruz de Mompox, renowned because of its goldsmithing tradition, indigenous groups and Spaniards experienced momentous encounters of individuals, metallurgical technologies and knowledge. However, little is known concerning colonial metallurgy, its continuities and changes with regards to the pre-Columbian period. Here we present the analytical characterization of five crucibles recovered in Mompox, together with discussion of relevant archival evidence. We find evidence for the local manufacture of crucibles as well as for the melting of unrefined gold dust, tumbaga (gold-copper-silver alloys) and silver. These metallurgical practices illustrate some likely illegal activities, continuities with pre-Columbian traditions in the use of tumbagas, and the Spanish-led introduction of silver in northern Colombia. It is argued that metallurgical remains can be informative of wider social and economic negotiations that engaged indigenous peoples, mestizos and Spaniards, which are critical to understand the configuration of the colonial reality.     

The Utility of Discourse Analysis to Heritage Studies: The Burra Charter and Social Inclusion

This paper reviews the methodological utility of Critical Discourse Analysis (CDA) in heritage studies. Using the Burra Charter as a case study we argue that the way we talk, write and otherwise represent heritage both constitutes and is constituted by the operation of a dominant discourse. In identifying the discursive construction of heritage, the paper argues we may reveal competing and conflicting discourses and the power relations that underpin the power/knowledge relations between expertise and community interests. This identification presents an opportunity for the resolution of conflicts and ambiguities in the pursuit of equitable dialogues and social inclusion.     

The visual dehumanisation of refugees

Dealing with refugees is one of the most contested political issues in Australia. We examine how media images of asylum seekers have framed ensuing debates during two crucial periods over the past decade. By conducting a content analysis of newspaper front pages we demonstrate that asylum seekers have primarily been represented as medium or large groups and through a focus on boats. We argue that this visual framing, and in particular the relative absence of images that depict individual asylum seekers with recognisable facial features, associates refugees not with a humanitarian challenge, but with threats to sovereignty and security. These dehumanising visual patterns reinforce a politics of fear that explains why refugees are publicly framed as people whose plight, dire as it is, nevertheless does not generate a compassionate political response.

如何对待难民是澳大利亚一个最具争议的政治话题。我们考察了在过去十年中的两个关键时期中媒体的避难者形象是如何影响接下来辩论的。根据笔者对报纸的头版所做的内容分析,避难者主要被再现为中、大型群体,多集中在船上。我们认为,这样的视觉形象、尤其是缺少描画个体避难者脸部特征的形象,不会将避难者同人道主义问题联系起来,而只会同威胁主权及安全相链接。这类非人性化的视觉模式强化了恐惧的政治,这也解释了为什么公众认为难民境遇凄惨,却不给他们政治上的同情。     

Biomechanical insights into activity and long distance trade in the south-central Andes (AD 500–1450)

Long distance trade has been attributed important social and economic roles in the pre-colonial south-central Andes, but how these trade networks were operated and organised, and the roles played by different populations and social groups (e.g. elites), remain uncertain. This study aims to offer new perspective on these questions through biomechanical analyses of human skeletal remains from a probable key site in these networks, San Pedro de Atacama (SPdA). Groups that were more intensively involved in long distance trade are expected to have been more habitually mobile, and thus to show greater robusticity and less circular lower limb bone cross-sections. Lower limb biomechanical properties of elite and non-elite Middle Horizon groups (MH, AD 500–1000) were compared with subsequent transitional MH-Late Intermediate Period (LIP, AD 1000–1450) and LIP groups from SPdA, and with LIP groups from Pica-8 and the Azapa Valley. The results indicate that MH populations from SPdA had less robust lower limbs and were by inference less mobile than their successors, with no differences between elite and non-elite, while robusticity was elevated in the MH-LIP transition group. Alternative explanations for the results, such as changes in herding activities, cannot be entirely discounted based on current evidence, but the results are consistent with hypotheses that SPdA may have served as a hub on long distance trade networks during the MH, before residents became more actively involved in long distance trade following the collapse of key links with the Tiwanaku polity. The results also indicate similar levels of robusticity among LIP populations at SPdA, Pica-8 and in the Azapa Valley, implying they may have been involved in trading activities to a similar extent, and perhaps to a greater extent than SPdA MH groups, as regional intergroup relationships changed.     

Corporate social responsibility in tourism post-2015: a Development First approach

Most large tourism businesses have corporate social responsibility (CSR) initiatives that advance environmental, economic and social sustainability. Existing research shows that initiatives often tend to be ad hoc, however, and linked to cost-savings and the reputation of the business. We suggest that this approach equates with Tourism First planning. In response to the greater demands being placed on businesses to act responsibly in the post-2015 era, we propose a Development First framework for CSR that is adapted from Peter Burns’ tourism planning model. This framework has a holistic, sustainable and people-centred focus and enables geographers and other social scientists to analyse the potential for initiatives to lead to positive, long-term development outcomes in different localities.     

On bad terms: Problems and solutions within zooarchaeological bone surface modification studies

The identification of butchery marks in the zooarchaeological record has consistently been debated. Much experimental work has been done to understand the causal agents behind some bone surface modifications, but recent controversies show that there is still no consensus. Terminology is not consistent between researchers, and there is ambiguity in how characteristics of marks are described and interpreted. There is also a lack of understanding of what causes individual variables within marks made by different agents, which is compounded by mark morphologies being described in terms that imply their causality. This paper examines these two problems in light of historic and current trends in the taphonomic literature, and recommends ways to describe marks that will facilitate more effective communication between researchers. It is proposed that greater standardisation within zooarchaeology is needed in seven key areas, and that this is the best avenue for moving into a new phase of taphonomic research.     

An Australian geography of unhealthy housing

Housing problems, such as affordability, poor quality of condition, or damp, are key determinants of health and wellbeing. Importantly, though, a growing body of research has shown that unhealthy housing is the combined result of multiple housing problems acting together. Although the spatial distribution of discrete housing problems is well established, little is known of Australia's geography of unhealthy housing. We have previously defined and validated an Australian Index of Housing Insults, which captures the multiple ways in which housing adversely influences individual health—including, but not limited to, people's tenure security, affordability, quality, and neighbourhood characteristics. Using the Household Income and Labour Dynamics in Australia (HILDA) dataset, a nationally representative longitudinal survey of Australian households, this paper describes Australia's geography of unhealthy housing. The analysis examines the prevalence, characteristics, and distribution of the population who are vulnerable to unhealthy housing. Our findings reveal both a worsening landscape of households at risk because of their accommodation and a changing pattern of unhealthy housing in Australia over time. The paper considers how these findings may impact future policy settings and the potential to improve the health of Australia's population through targeted housing interventions.     

Archaeometric study of natural hydraulic mortars: the case of the Late Roman Villa dell’Oratorio (Florence,Italy)

This paper shows the results of a multidisciplinary study carried out on the mortars from the Late Roman Villa dell’Oratorio (fourth-sixth ad), an aristocratic mansion built in the lower Valdarno (Florence, Italy). Thirty-one bedding mortar and plaster samples were analysed through optical microscopy, thermogravimetric analysis, X-ray powder diffraction and scanning electron microscopy with energy-dispersive X-ray spectroscopy for determining the chemical, mineralogical and petrographic characteristics, while their main physical properties were measured by geotechnical procedures. The collected data indicates that the analysed mortars are made up of very fine to coarse river sand aggregate mixed with white to yellowish-white natural hydraulic lime binder mainly consisting of mixtures of prevailing calcite and hydraulic compounds. With regard to the origin of the raw materials, the aggregates were recognized to be selected Arno river sands, and the binders are the burning product of a local marly limestone (ex Alberese). Therefore, the mortars of the Late Roman Villa dell’Oratorio are one of the first uses of natural hydraulic lime in the lower Valdarno.
