Distinguishing Species of Geoemyclid and Trionychid Turtles from Shell Fragments:Evidence from the Pleistocene at Niah Caves, Sarawak

Fragments of chelonian carapace and plastral dermal plates are well-represented from archaeological sites in the world's dry and wet tropics. However, although these bones are easily identified at an element level, few archaeological reports have explored the potential of using features of form and surface sculpturing as a way to refine that identification to genus or species. The ability to achieve such a refinement would benefit environmental and human subsistence strategy models alike. The objective of the current paper was to isolate recurrent and readily visible surface characteristics on the dermal plates from a selection of commonly occurring Southeast Asian hard- and soft-shelled turtles. Using these criteria, analysis is made of the chelonian assemblage from pre- and post-Last Glacial Maximum (LGM) cultural deposits in the West Mouth of Niah Cave.

Disentangling the Harrisson Archive to Interpret the Spatial and Temporal Distribution of Vertebrate Remains at Niah Caves, Sarawak

During the 1950s and 1960s, excavations by the Sarawak Museum at Niah Cave in northwest Borneo produced an enormous archive of records and artefacts, including in excess of 750,000 macro- and micro-vertebrate remains. The excellent state of preservation of the animal bone, dating from the Late Pleistocene (c. 40 kya) to as recently as c. 500 years ago had the potential to provide unparalleled zooarchaeological information about early hunter-gatherer resource procurement, temporal changes in subsistence patterning, and the impact of peoples on the local and regional environment in Island Southeast Asia. However, the coarse-grained methods of excavation employed during the original investigations and the sheer scale of the archaeological record and bone assemblages dissuaded many researchers from attempting to tackle the Niah archives. This paper outlines how important information on the nature of the archaeological record at Niah has now finally been extracted from the archive using a combination of zooarchaeological analysis and reference to the extensive archaeological records from the site.

Nong Thale Pron - a key site from southern Thailand for studying monsoon variability during the past 15000 years

Studies of marine sediments, cave speleothemes, annually laminated corals, and tree rings from Asian monsoon regions have added knowledge to our understanding of the factors that control inter-annual to millennial monsoon variability in the past and have provided important constraints for climate modeling scenarios. In contrast, the spatial and temporal pattern of sub-millennial scale monsoon variability and its impact on land cover in SE Asia are still unresolved. This shortcoming stems from the fact that temporally well-resolved paleo-environmental studies are missing from large parts of SE Asia, especially from Thailand. Given that global and regional climate models are increasingly using terrestrial paleo- data to test their performance, past changes in land cover are therefore important variables to better understand feedbacks between different Earth systems. We obtained sediments from Lake Nong Thale Pron, in southern Thailand (8º 10`N, 99 º23`E; 380 m.asl). The aim of our study is to reconstruct lake status changes and to evaluate whether the extent of these changes are linked to known shifts in monsoon intensity and variability. Preliminary results show that lake infilling started more than 15,000 years ago and that the sediments cover the last deglaciation and the Holocene. Current analyses include Itrax XRF core scanning, loss-on-ignition (LOI at 950 and 550ºC), CN elemental and isotopic composition. We expect that our results will be able to give a picture of how the lake's status has changed over time and whether the extent of these changes is linked to known shifts in monsoon intensity and variability.

Progress towards improving chronologies for marine sediment records.

The North Atlantic has played a key role in abrupt climate changes due to the sensitivity of the Atlantic Meridional Overturning Circulation (AMOC) to the location and strength of deep water formation. It is crucial for modelling future climate change to understand the role of the AMOC in the rapid warming and gradual cooling cycles known as Dansgaard-Oescher (DO) events which are recorded in the Greenland ice cores. However, palaeoceanographic research into DO events has been hampered by the uncertainty in timing due largely to the lack of a precise chronological time frame for marine records. While tephrochronology provides links to the Greenland ice core records at a few points, radiocarbon remains the primary dating method for most marine cores. Due to variations in the atmospheric and oceanic 14C concentration, radiocarbon ages must be calibrated to provide calendric ages. The IntCal Working Group provides a global estimate of ocean 14C ages for calibration of marine radiocarbon dates, but the variability of the surface marine reservoir age in the North Atlantic particularly during Heinrich or DO events, makes calibration uncertain. In addition, the current Marine09 radiocarbon calibration beyond around 15 ka BP is largely based on 'tuning' to the Hulu Cave isotope record, so that the timing of events may not be entirely synchronous with the Greenland ice cores. The use of event-stratigraphy and independent chronological markers such as tephra provide the scope to improve marine radiocarbon reservoir age estimates particularly in the North Atlantic where a number of tephra horizons have been identified in both marine sediments and the Greenland ice cores. Quantification of timescale uncertainties is critical but statistical techniques which can take into account the differential dating between events can improve the precision. Such techniques should make it possible to develop specific marine calibration curves for selected regions.

Modulating mythology in a post-traumatic era: Murals and re-imaging in Northern Ireland.

Arguably the most ancient of the social media, wall paintings have been a persistent vehicle of cultural meaning management. The dynamics of myth markets are reflected in the sectarian murals of Northern Ireland. In this paper, we draw from consumer research literature on mythology and street art to explore the continuous revision of these wallscapes that seeks to address the enduring contradictions of civic ideology in contested political space. In particular, we focus on the use of classical, historical and pop-cultural mythologies to transform private space into public place. We examine the decommissioning of murals occurring in the wake of the Peace Accords, and speculate on the implications of the creation of a shared mythology for the future of mural painting and the state.

Remedios Varo's Feminine, Spiritual Quest

Remedios Varo occupies a marginal position in the Surrealist canon, despite her direct involvement with Breton’s circle and in spite of the fact that her work is attributed a universal significance. It has been interpreted as representing a journey towards identity and freedom, a search for female empowerment, and as a spiritual quest. Moreover, critical focus on the mythic/exoteric ‘female’ quest has been to the detriment of the mystical/esoteric significance of the paintings. This article argues that it is in the combination of these strands that Varo’s radicalism might be found. It shows that by presenting a female, spiritual quest for enlightenment—which exists apart from a traditionally male-dominated, western religious schema—Varo circumvented her ordained role within the artistic, spiritual, and political communities of which she was a part.

Forced Displacement, Suffering and the Aesthetics of Loss

This article investigates how artists have addressed shocking experiences of displacement in different political contexts. Drawing on the notion of ‘the aesthetics of loss’ (Köstlin, 2010), it examines and compares the different aims, desires and strategies that have shaped the histories and social lives of paintings, memorial statues, installations and other artefacts. The analysis identifies a mode of artistic engagement with the sense of a ‘loss of homeland’ that has been commonly felt amongst Sudeten German expellees, namely the production and framing of visual images as markers of collective trauma. These aesthetics of loss are contrasted with the approach taken by the Dutch artist Sophie Ernst in her project entitled HOME. Working with displaced people from Pakistan, India, Palestine, Israel and Iraq, she created a mnemonic space to stimulate a more individualistic, exploratory engagement with the loss of home, which aimed, in part, to elicit interpersonal empathy. To simply oppose these two modes of aesthetic engagement, however, would ignore the ways in which artefacts are drawn into different discursive, affective and spatial formations. This article argues for the need to expose such dynamic processes of framing and reframing by focusing on the processual aspects of aestheticisation with attention to the perspective of loss.

A audácia de ser diferente: a escrita obsessiva de Ana Teresa Pereira

A presente tese tem como objetivo estudar a obra da escritora madeirense Ana Teresa Pereira. Partindo da leitura integral dos seus livros, que se interligam formando um todo caraterizado por uma unidade intrínseca e obsessiva, e analisando especificamente a obra publicada entre 1989 e 2008, procurámos demonstrar os tópicos que permitem classificar a sua poética como uma escrita obsessiva e audaz, sob o ponto de vista do que de mais espantoso as expressões podem ter. Estamos perante uma obra cuja indivisibilidade labiríntica se entretece com a paixão obsessiva pela Arte, em particular, pela Literatura, pelo Cinema, pela Pintura e pela Música.

Introduction: Mapping Gwen John: Lives, Lines and Images

Nomadic Narratives, Visual Forces explores issues, questions, and problems emerging in the analysis of epistolary and visual narratives. This book focuses in particular on Gwen John's letters and paintings. It offers an innovative theoretical approach to narrative analysis by drawing on Foucault's theory of power, Deleuze and Guattari's analytics of desire, and Cavarero's concept of the narratable self. Furthermore, it examines the use of letters as documents of life in narrative research and highlights the dynamics of spatiality in the constitution of the female self in art. This study brings together theoretical insights that emerge from the analysis of life documents - some of them previously unpublished - combining innovative research with specific methodological suggestions on doing narrative analysis.

Looking behaviour and preference for artworks: The role of emotional valence and location

The position of an item influences its evaluation, with research consistently finding that items occupying central locations are preferred and have a higher subjective value. The current study investigated whether this centre-stage effect (CSE) is a result of bottom-up gaze allocation to the central item, and whether it is affected by item valence. Participants (n=50) were presented with three images of artistic paintings in a row and asked to choose the image they preferred. Eye movements were recorded for a subset of participants (n=22). On each trial the three artworks were either similar but different, or were identical and with positive valence, or were identical and with negative valence. The results showed a centre-stage effect, with artworks in the centre of the row preferred, but only when they were identical and of positive valence. Significantly greater gaze allocation to the central and left artwork was not mirrored by equivalent increases in preference choices. Regression analyses showed that when the artworks were positive and identical the participants’ last fixation predicted preference for the central art-work, whereas the fixation duration predicted preference if the images were different. Overall the result showed that item valence, rather than level of gaze allocation, influences the CSE, which is incompatible with the bottom-up gaze explanation. We propose that the centre stage heuristic, which specifies that the best items are in the middle, is able to explain these findings and the centre-stage effect.
