    Aspects of the late Atlantic Iron Age

    Get PDF
    The Scottish Atlantic Iron Age is recognised as falling into four periods, the EIA, MIA, LIA I and LIA II. Least is known of the LIA I, the immediate post-broch period. Original analysis of the C-14 record confirms these divisions; they result as a combination of the effects of the Trondheim calibration curve but mainly the history of archaeological survival and previous excavation strategy. A large data base of pins and combs is examined and analysed, following on the earlier work of Stevenson (1955a), because these are some of the more ubiquitous and chronologically sensitive artefacts belonging to the LIA. This provides the basis for a reconsideration of the nature of LIA settlement throughout the Atlantic Province as a whole, more particularly in the study area of Orkney and Caithness. There are still severe problems in recognising LIA, particularly LIA I activity. This analysis forms the basis for a case study of Orkney and Caithness from around the early centuries of the first millennium BC to the eighth or ninth century AD. A scheme is suggested for the structural developments witnessed over this period, and on the basis of the general trends observed, a social interpretation is put forward. An attempt is made to apply Fields of Discourse, which is contrasted with previous work in this area, because of its sound methodological approach. Archaeological application of the technique of access analysis is described and used to investigate how the use of space structured and reproduced these changing social relations. The shift from locally based power sources to more centralised, in relation to Orkney and Caithness more distant, sources of authority is demonstrated, and related to the development of the southern Pictish kingdom. This change reflects the move from intensive to extensive sources of power. Other aspects of social reproduction are examined to see if they fit within this framework. On analogy with contemporary situations elsewhere and the evidence to hand, the means by which this power may have been exercised, specifically changing agricultural practice and land tenure, and the ideological power of Christianity are speculated upon

    Concrete and non-concrete: exploring the contemporary authenticity of historic replicas through an ethnographic study of the St John's Cross replica, Iona

    What do we actually know about how replicas of historical objects and monuments 'work' in heritage contexts, in particular their cultural significance and intangible values? In this article we examine this question drawing on ethnographic research surrounding the 1970 concrete replica of the eighth-century St Johnā€™s Cross on Iona, Scotland. Challenging traditional precepts that seek authenticity in qualities intrinsic to original historic objects, we show how replicas can acquire authenticity and 'pastness', linked to materiality, craft practices, creativity, and place. We argue that their authenticity is founded on the networks of relationships between people, places and things that they come to embody, as well as their dynamic material qualities. The cultural biographies of replicas, and the 'felt relationships' associated with them, play a key role in the generation and negotiation of authenticity, while at the same time informing the authenticity and value of their historic counterparts through the 'composite biographies' produced. As things in their own right, replicas can 'work' for us if we let them, particularly if clues are available about their makersā€™ passion, creativity and craft

    The untold heritage value and significance of replicas

    Get PDF
    This article focuses on the fraught questions surrounding replicas and their use in heritage contexts, drawing on the first in-depth qualitative study of a historic replica, the 1970 concrete St John's Cross, Iona. We examine how replicas 'work' and unravel the part that social relations, place and materiality play in the production and negotiation of authenticity. The research shows that replicas are important objects in their own right, acquiring value, authenticity and aura. The 'life' of a replica generates networks of relationships between people, places and things, including the original historic object, becoming part of its 'composite' biography. While the underlying human stories of creativity, skill and craftsmanship are rendered invisible when replicas are treated as mere surrogates, we argue that these 'life-stories' should be incorporated into future conservation, management and interpretation. The article spells out practical advice and guidance for heritage professionals who find themselves dealing with replicas

    The curatorial consequences of being moved, moveable or portable: the case of carved stones

    Get PDF
    It matters whether a carved stone is moved, moveable or portable. This influences perceptions of significance and of form and nature ā€“ is it a monument or an artefact? This duality may in turn affect understanding and appreciation of the resource. It has implications for how and if carved stones can be legally protected, who owns them, where and how they are administered, and by whom. The complexities of the legislation mean that all too often this is also a grey area. This paper explores these curatorial issues and their impact

    Understanding choice in assistive technology service provision: considerations for research methodology

    Get PDF
    The adoption of choice as a policy principle in disability services reforms warrants research into the practical implications for assistive technology provision. This paper outlines methodological considerations for the investigation of how choice is constructed and experienced in assistive technology provision. It argues for an interpretive approach that considers the interactions between stakeholders and the influence of contextual factors on choices over time. Understanding stakeholdersā€™ interpretations and contextual factors that affect their choice behaviors in AT acquisition will assist the interpretation of AT outcomes. It may also assist in efforts to increase the usability of AT services, develop improved service delivery models, and target policy initiatives to support AT provision practices

    Toxicity of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in the developing male Wistar(Han) rat II: chronic dosing causes developmental delay

    Get PDF
    We have investigated whether fetal exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) causes defects in the male reproductive system of the rat, using chronically exposed rats to ensure continuous exposure of the fetus. 5-6 week old rats were exposed to control diet, or diet containing TCDD, to attain an average dose of 2.4, 8 and 46 ng TCDD kg-1 day-1 for twelve weeks, whereupon the rats were mated, and allowed to litter; rats were switched to control diet after parturition. Male offspring were allowed to develop until kills on PND70 (25 per group), or PND120 (all remaining animals). Offspring from the high dose group showed an increase in total litter loss, and the number of animals alive on post-natal day (PND) 4 in the high dose group was ~26% less than control. The high and medium dose offspring showed decreased weights at various ages. Balano-preputial separation was significantly delayed in all three dose groups, compared to control. There were no significant effects of maternal treatment when the offspring were subjected to a functional observational battery, or learning tests, with the exception that the high dose group showed a deficit in motor activity. 20 rats per group were mated to females, and there were no significant effects of maternal treatment on the fertility of these rats, nor on the F1 or F2 sex ratio. Sperm parameters at PND70 and 120 showed no significant effect of maternal treatment, with the exception that there was an increase in the proportion of abnormal sperm in the high dose group at PND70; this is associated with the developmental delay in puberty in this dose group. There were no remarkable findings of maternal treatment on organ weights, with the exception that testis weights were reduced by ~10% at PND70 (but not PND120), and although the experiment was sufficiently powered to detect small changes, ventral prostate weight was not reduced. There were no significant effects of maternal treatment upon histopathological comparison of high dose and control group organs. These data confirm that developmental exposure to TCDD shows no potent effect on adult sperm parameters or accessory sexual organs, but show that delay in BPS occurs after exposure to low doses of TCDD, and this is dependent upon whether TCDD is administered acutely or chronically

    Episodic Memory Measures Complement Structural and Functional MRI for Predicting Cognitive Decline in Apolipoprotein E Īµ4 Carriers

    Apolipo-protein E (APOE) ?4 allele carriers demonstrate greater risk for cognitive decline and Alzheimer\u27s disease than non-carriers. However, factors associated with risk of decline among APOE ?4 carriers are not well-known. In this longitudinal study, we investigated whether discrete aspects of baseline episodic memory performance and structural (sMRI) and function (fMRI) magnetic resonance imaging were associated with cognitive decline in older APOE ?4 carriers and non-carriers. Seventy-eight healthy older adults underwent cognitive testing at baseline and after 18 months, baseline serum APOE genotyping, manually-traced hip-pocampal volume measurement from sMRI, and task-activated fMRI. Cognitive decline was defined as a one SD or greater reduction from baseline on at least one of three cognitive measures at follow-up (Rey Auditory Verbal Learning Test [AVLT] Delayed Recall and Trials 1-5 Sum, Mattis Dementia Rating Scale-2 Total Score). Declining APOE ?4 carriers (n=14) exhibited reduced hippocampal volume (

    Challenges of user-centred assistive technology provision in Australia: shopping without a prescription

    Get PDF
    Purpose: People with disability have a right to assistive technology devices and services, to support their inclusion and participation in society. User-centred approaches aim to address consumer dissatisfaction and sub-optimal outcomes from assistive technology (AT) provision, but make assumptions of consumer literacy and empowerment. Policy discourses about consumer choice prompt careful reflection, and this paper aims to provide a critical perspective on user involvement in assistive technology provision. Methods: User-centred approaches are considered, using literature to critically reflect on what user involvement means in AT provision. Challenges at the level of interactions between practitioners and consumers, and also the level of markets and policies are discussed, using examples from Australia. Results: There is no unanimous conceptual framework for user-centred practice. Power imbalances and differing perspectives between practitioners and consumers make it difficult for consumers to feel empowered. Online access to information and international suppliers has not surmounted information asymmetries for consumers or lifted the regulation of publicly funded AT devices. Conclusions: Ensuring access and equity in the public provision of AT is challenging in an expanding market with diverse stakeholders. Consumers require personalised information and support to facilitate their involvement and choice in AT provision. Implications for Rehabilitation: Variations in approaches informing AT provision practices have a profound impact on equity of access and outcomes for consumers. An internationalised and online market for AT devices is increasing the need for effective information provision strategies and services. Power imbalances between practitioners and consumers present barriers to the realisation of user-centred practice
