Unbearable pressures on paradise? : Tourism and heritage management in Luang Prabang, a world heritage site

This article critically appraises and evaluates tourism strategies and heritage management in Luang Prabang, Lao People’s Democratic Republic, a Unesco-designated ‘world heritage’ city. Luang Prabang is widely regarded as one of the most significant heritage cities in Southeast Asia. The city is renowned for its Buddhist and royal culture and also its historic vernacular Lao, French, and Lao-French architecture. The city earned world heritage status in 1995, but since that time the boom in in-bound Asian tourism has put pressures on Luang Prabang’s authenticity and, for some, called into question the validity of its world heritage status. This article examines these substantial and wide-ranging pressures and argues that the growth in tourism and the treatment of Luang Prabang’s heritage are symptoms of broader regional processes of political and economic change, including the expansion of Chinese and Korean investments and the growth of intra-regional tourism. The authors argue that it is unreasonable to expect traditional heritage management mechanisims, including the world heritage listing, to be able to cope with the pressures on sites like Luang Prabang. The very least that is required, the authors contend, is an expanded understanding of the context in which heritage places sit, and the authors make a case that the cultural landscapes approach, combined with explicit concerns for intangible heritage and poverty alleviation, must be at the core of any strategy for long-term protection of the city’s cultural values.

Thin film drainage : hydrodynamic and disjoining pressures determined from experimental measurements of the shape of a fluid drop approaching a solid wall

Accurate measurements of the shape of a mercury drop separated from a smooth flat solid surface by a thin aqueous film reported recently by Connor and Horn (Faraday Discuss. 2003, 123, 193-206) have been analyzed to calculate the excess pressure in the film. The analysis is based on calculating the local curvature of the mercury/aqueous interface, and relating it via the Young-Laplace equation to the pressure drop across the interface, which is the difference between the aqueous film pressure and the known internal pressure of the mercury drop. For drop shapes measured under quiescent conditions, the only contribution to film pressure is the disjoining pressure arising from double-layer forces acting between the mercury and mica surfaces. Under dynamic conditions, hydrodynamic pressure is also present, and this is calculated by subtracting the disjoining pressure from the total film pressure. The data, which were measured to investigate the thin film drainage during approach of a fluid drop to a solid wall, show a classical dimpling of the mercury drop when it approaches the mica surface. Four data sets are available, corresponding to different magnitudes and signs of disjoining pressure, obtained by controlling the surface potential of the mercury. The analysis shows that total film pressure does not vary greatly during the evolution of the dimple formed during the thin film drainage process, nor between the different data sets. The hydrodynamic pressure appears to adjust to the different disjoining pressures in such a way that the total film pressure is maintained approximately constant within the dimpled region.

Reconstructing the south : how commercial myths compete for identity value through the ideological shaping of popular memories and countermemories

This study explicates the coconstitutive relationships between commercial myth- making and popular memory that arise through myth market competitions for identity value. We develop a genealogical analysis of the representational strategies and ideological rationales that two prominent New South mythmakers use to shape popular memories in relation to their competitive goals and to efface counter- memories that contradict their mythologized representations. We then derive a conceptual model that highlights competitive, historical, and ideological influences on commercial mythmaking and their transformative effects on popular memory, which have not been addressed by prior theorizations of the meaning transfer process.

Blood pressure and cognitive function: the role of central aortic and brachial pressures

Central (aortic) blood pressures differ from brachial pressures and may be more relevant to the study of cognitive function, given that blood is delivered to the brain through the central large arteries. Pulse-pressure amplification reflects the augmentation of blood pressure between the central and peripheral arteries, which diminishes with aging. We aimed to determine the association between central blood pressure and cognitive function in independently living adults aged 20 to 82 years (N = 493). In adjusted regression models, higher central systolic pressure and higher central pulse pressure were each associated with poorer processing speed, Stroop processing, and recognition memory. Lower amplification was associated with poorer Stroop processing, working memory, and recognition memory. Higher brachial systolic pressure and brachial pulse pressure were both associated with poorer Stroop processing. In summary, central pressures and amplification were sensitive indicators of cognitive aging, predicting aspects of cognitive performance not predicted by brachial blood pressure.

Mobile teachers, teacher identity and international schooling

Mobile Teachers, Teacher Identity and International Schooling focuses on the increased mobility of teachers and curriculum and what it means for the expansion of international schooling. In the early 21st century, educational institutions have been transformed by technological innovation and global interconnectivity. The demographic, ideological, economic and cultural flows that integrate local and global interconnections have consequences for the ways in which educational policy, theories and practice can be understood and take place locally. The everyday lives of practitioners, parents and students; the institutions in which they are educated and work; and the sociocultural and ideological contexts in which they work, are all consequently changing. The manifestation of these changes – as evident in the work and lives of teachers within specific cultural contexts and education systems; in their implications for educational theory and methodology; and their consequences for policy, programs, practice and research in education – are the focus of this book.This book explores the mobility of curriculum, pedagogies, ideas and people that represent and mediate the impact of Global uneven flows and movements through, in, and for school education, and the concepts and practices which frame that transformation. The particular focus of the book is on how these flows inform the ways individuals negotiate their identities, cultures and languages in different national and educational contexts. Education systems and the educational experiences offered by schools are being reconfigured due to multiple pressures. What do these moves to mobilise and to work transnationally mean in terms of educational provision, possibilities and practice?
