‘You have to make a new way of life’: women's drug treatment programmes as therapeutic landscapes in Canada

The concept of the ‘therapeutic landscape’ has been widely applied by health geographers over the past decade and a half. Despite its broad application, the concept has been criticized. Some scholars, for example, have argued that it adopts an overly positive view of the health effects of therapeutics settings. Others have noted a lack of attention to gender. In this article we respond to these limitations by engaging with feminist research on women and drug use to critically examine women's experiences of the therapeutic space of drug treatment programmes. Drawing on in-depth interviews and participant observation conducted at two sites in southern Ontario, we examine the ways in which programmes' organizational logics, daily routines and social spaces are shaped by gendered assumptions about the nature of, and solutions to, women's drug use. In so doing, we contribute to a more nuanced and critically informed understanding of such landscapes.     

Home sounds: experiential practices and performativities of hearing and listening

We argue that a closer attention to the everyday visceral experiences of hearing and listening offers new insights into geographies of home and practices of sustainability. We suggest that this approach is significant to understanding how sound helps to assemble and reassemble the relationships that comprise home. We concentrate on a group of 10 amenity-led migrants in their ‘new coastal home’ in Bermagui, New South Wales, Australia. Each participant recorded a sound diary composed of their everyday sounds. Our interpretation explores the visceral connections in the processes of making bodies feel ‘at home’. First, we discuss how the rhythmic affordances of both human and non-human sounds help configure and reconfigure the spatiality and temporality of home. Second, our interpretation explores how sound is bound up with sustainability politics of homemaking. We investigate experiential practices and performativities of listening and hearing that may help constitute and reconstitute ‘a’ subject. This approach extends current thinking that encourages engagement with the corporeal, affective and emotional dimensions of home.     

Strontium isotope ratios in fossil teeth from South Africa: assessing laser ablation MC-ICP-MS analysis and the extent of diagenesis

This study tests the precision and accuracy of laser ablation multi-collector inductively coupled plasma mass spectrometry (LA-MC-ICP-MS) for measuring strontium isotope ratios (⁸⁷Sr/⁸⁶Sr) in fossil teeth from Swartkrans and Sterkfontein in South Africa, and explores the extent of diagenesis in these specimens. Compared to solution MC-ICP-MS or thermal ionization mass spectrometry (TIMS) methods, LA-MC-ICP-MS can be faster and less expensive, but has lower precision and accuracy. We found that ⁸⁷Sr/⁸⁶Sr ratios in fossil rodent teeth measured by LA-MC-ICP-MS were offset from solution values by a mean of 0.0005 ± 0.0010 (2σ). Because of the very wide spread of biologically available ⁸⁷Sr/⁸⁶Sr ratios (∼0.710 to ∼0.790) in the region, LA-MC-ICP-MS is more than sufficient for assessing the geographic origins of the fossil rodents. The concentration of strontium in modern and fossil enamel from the area is statistically indistinguishable, as is the range of ⁸⁷Sr/⁸⁶Sr ratios in modern rodents and fossil rodents from Swartkrans. Thus, there is little evidence of diagenetic Sr in the fossil enamel. In contrast, the fossil dentine may contain up to ∼50% diagenetic strontium, although many dentine ⁸⁷Sr/⁸⁶Sr ratios are still far removed from the background cave value of 0.729. We propose that LA-MC-ICP-MS will also be of use for investigating the geographic origins of other, non-rodent fossil teeth from the Sterkfontein and Swartkrans collections, and may prove of similar utility at other suitable sites.     

Thermal range of coastal tourism resort microclimates

With considerable evidence demonstrating the intrinsic importance of weather and climate for tourist decision-making, the projected redistribution of climatic resources as a result of climate change is anticipated to have important consequences for temporal and spatial patterns of tourism demand. Some of the world's leading coastal tourism destinations (Mediterranean and Caribbean) have been identified as becoming ‘too hot’ for tourism. However, the microclimates of coastal tourism areas have not been considered by such assessments. With a focus on thermo-physiologically relevant climatic parameters, this paper examines the adaptive range of microclimatic conditions available in two coastal resort settings in the Caribbean islands of Barbados and Tobago. Recorded weather parameters include air temperature, black globe temperature, relative humidity, and wind speed. The microclimatic results, which are presented using the Universal Thermal Climate Index (UTCI), show that hourly thermal conditions can range up to 4 °C in different outdoor areas of the resort property (beach, garden, pool, cabana). This is salient in terms of characterizing tourism destinations for climate change assessments, as the results reveal that thermal conditions can vary at the micro-scale of a coastal resort, with the ability for tourists to attain thermally comfortable conditions within a single resort property. When a location becomes thermally uncomfortable (i.e. too hot), tourists can change their location (e.g. move from the pool to the beach), providing an onsite adaptive range between 1 °C and 4 °C. The results also demonstrate that thermo-physiologically relevant climatic parameters provide a more precise estimate of the available range of thermal comfort than is inferred from ambient temperature alone. The findings are discussed in the context of tourists’ climatic preferences and reveal that the microclimatic conditions recorded in this study (UTCI 29–36 °C) are well within tourists’ preferred thermal conditions and do not exceed tourists’ thermal thresholds for coastal tourism.     

Human refugia in Australia during the Last Glacial Maximum and Terminal Pleistocene: a geospatial analysis of the 25–12 ka Australian archaeological record

A number of models, developed primarily in the 1980s, propose that Aboriginal Australian populations contracted to refugia – well-watered ranges and major riverine systems – in response to climatic instability, most notably around the Last Glacial Maximum (LGM) (∼23–18 ka). We evaluate these models using a comprehensive continent-wide dataset of archaeological radiocarbon ages and geospatial techniques. Calibrated median radiocarbon ages are allocated to over-lapping time slices, and then K-means cluster analysis and cluster centroid and point dispersal pattern analysis are used to define Minimum Bounding Rectangles (MBR) representing human demographic patterns. Exploring data between 25 and 12 ka, we find a refugia-type hunter-gatherer response during the LGM (∼23–18 ka) and again during the Antarctic Cold Reversal (ACR) (∼14.5–12.5 ka), with expansion in the intervening period. Several refugia persist between 25 and 12 ka, including (by Interim Biogeographic Regionalisation for Australia areas) Gulf Plains/Einasleigh Uplands, Brigalow Belt South, Murray Darling Depression, and Tasmanian Central Highlands. Others appear sporadically through the same period. These include South Eastern Highlands, NSW South Western Slopes, Sydney Basin, Warren, Murchison, Gascoyne, Central and Northern Kimberley, Ord Victoria Plain, Arnhem Plateau, MacDonnell Ranges and Central Ranges. The Pilbara may also have been a refugium during the LGM, but geospatial results are problematic for this region. Areas devoid of human activity (‘barriers’) include the main desert regions, especially in the south and west of the continent, although some of these may be the result of an absence of archaeological fieldwork. Point dispersal pattern analysis indicates a reduction in occupied territory of nearly 80% during the LGM. A reduction of close to 50% was also evident during the ACR. A large number of the refugia were in close proximity to glaciated areas during the LGM, and probably benefitted from increased summer snowmelt along the major river systems. The remaining refugia are likely the result of a range of local environmental and resource factors. We identify areas for future research, including a focus on regional studies to determine possible cryptic or idiosyncratic refugia emerging in phlyogeographic studies.     

'Ruling Theories Linger': Questioning the Identity of the Beaufort Inlet Shipwreck

From 1996 investigators of the Beaufort Inlet shipwreck, off North Carolina, USA, have suggested that the remains are those of the Queen Anne's Revenge , flagship of the pirate Blackbeard. Analysis of the published material, however, indicates that no concrete evidence has yet been found to support this identification and, moreover, shows a strong tendency towards Ruling Theory, whereby researchers seem to shape evidence to fit a pre-conceived identification. This article uses the Beaufort Inlet shipwreck as a case study in the dangers of Ruling Theory and how it can compromise scholarly objectivity, and thwart the generation of useful research questions. It also seeks to demonstrate the benefits of a clear, objective research design for project investigation and management.

Developing,designing and managing mixed tenure estates: implementing planning gain legislation in the Republic of Ireland1

This article reports the results of research on the implementation of recent legislation which enables Irish local authorities to require that up to 20% of new residential developments must be employed for social housing and for “affordable housing” for sale at below market value to low income households. The legislation will mean that most new residential developments will include several housing tenures. A survey of the number of mixed tenure estates constructed prior to its enactment indicates that, that without this legislation, few estates of this type would have been constructed in urban areas. Furthermore case studies of existing mixed tenure estates indicate that the prospects that this legislation can be successfully implemented are good. Opposition to tenure mixing among home buyers is less than some interest groups have claimed; there is little conflict between the residents of the different tenures in these estates and social housing managers and property developers hold similar views on the most appropriate design of these estates. However successful implementation of the legislation will require some reforms to arrangements for the planning and management of the developments subject to its provisions.     

Reconstructing faunal migrations using intra-tooth sampling and strontium and oxygen isotope analyses: a case study of modern caribou (Rangifer tarandus granti)

Isotopic analyses of incrementally developed dental tissues can be used to reveal patterns of movement and diet in animals. However, the suitability of these methods for the reconstruction of herd movements has not yet been demonstrated. Inter-individual behavioural and isotopic variability at the herd scale, and the implications for archaeological and palaeocological applications, can only be demonstrated through the testing of modern animals. In this pilot study, dual-element isotopic profiles were created from incrementally developed dental tissues of five individuals selected from a modern herd of migratory Alaskan caribou (Rangifer tarandus granti). Enamel from second and third molars from the individuals was sequentially sampled in order to reconstruct time-series isotopic profiles. Variation in the strontium (⁸⁷Sr/⁸⁶Sr) and oxygen (δ¹⁸O_CARB) isotope ratios of sequentially sampled enamel were compared to documented herd movement patterns and local geological and environmental conditions. Four individuals displayed the same general trends, although absolute isotopic values varied. One individual displays a very different trend and may represent a behavioural outlier or an immigrant from a semi-domesticated reindeer herd. The implications of this study to herd movement reconstruction in the past are discussed.
