Reconsidering the Geography of Tourism and Contemporary Mobility

Tourism is one of the world's largest legal industries. At the same time that tourism has grown so has its study, to the extent that there is debate as to whether it may constitute a discipline in its own right. Geographers have long contributed to the study of tourism. However, there is substantial concern over the development of the sub‐discipline and how tourism is conceptualised. A framework for understanding tourism in relation to contemporary human mobility over space and time is provided. This framework bears strong relationships to research on time geography as well as to work on diaspora and transnationalism. Some of the implications of incorporating tourism within the framework of mobility are outlined with respect to mobility as a form of capital, the relationships between different forms of mobility, and an improved understanding of tourism's impacts at all stages of the travel process rather than just at the destination.     

The Historical Snow Survey of Great Britain: Digitised Data for Scotland

Abstract

Mountain snowline is important as it is an easily observable measure of the phase state of water in the landscape. Changes in seasonal snowline elevation can indicate long-term trends in temperature or other climate variables. Snow-cover influences local flora and fauna, and knowledge of snowline can inform management of water and associated risks. Between 1945 and 2007 voluntary observers collected a subjective record of snow cover across Great Britain called the Snow Survey of Great Britain (SSGB). The original paper copy SSGB data is held by the Met Office. This article details the digitisation of the Scottish SSGB data, its spatial and temporal extents, and a brief example comparison of Met Office snow-lying gridded data. The digitised SSGB data are available from the Met Office authors.     

Spatial and environmental impacts on adverse birth outcomes in Ontario

This study assesses the overall spatial variations and neighbourhood‐level “hot spots” of low birth weight and preterm birth incidence within three public health units in Ontario, Canada. The analysis uses a stepwise approach of intra‐class correlation analysis, a spatial scan statistic, and multilevel spatial modeling. Results show that neighbourhood level variation accounts for only 2–3 percent of the total variation of adverse birth outcomes in the study area. However, strong spatial autocorrelation is observed at the neighbourhood level, and spatial clusters of relatively high adverse birth outcome rates exist in areas that are associated with environmental risks, including pollution sources and proximity to highways. Thus, although estimated neighbourhood impacts on adverse birth outcomes are small compared with those of individual‐level risks, local high potential environmental risk areas are identifiable. Environmental surveillance and spatial statistical analysis should be conducted regularly by local health authorities to identify and monitor the impact of environmental changes on health in general and on birth outcomes in particular. Specific community‐oriented health interventions may be required to reduce observed local health impacts.     

A reader in international relations and political theory

Jerusalem is the holy city for Leo Strauss. It is the symbol of Judaism; moreover it is a root of Western culture together with Athens. But it would be wrong to label Strauss' philosophical thought with such definitions as ‘Jewish philosophy’. Therefore it is surprising that many contemporary interpreters strive to find a confessional or religious foundation in Strauss' thought. On the contrary, many of Strauss's texts testify his choice in favour of Athens, i.e., of philosophy. Yet the choice of Athens does not imply a rejection of Jerusalem. Strauss is convinced that Jerusalem plays a central role in Western civilisation and considers the indifference to religion and the ideologisation of philosophy completed in the modern age as causes of Western crisis, i.e., of contemporary nihilism. Philosophy and religion are forced to live side by side (like philosophy and politics) because neither reason nor revelation can express the ultimate word on the good and the just, i.e., on truth.     

The influence of temperature on rehydroxylation [RHX] kinetics in archaeological pottery

Almost all archaeological ceramics undergo slow, progressive rehydroxylation by chemical combination with environmental water. The reaction is accompanied by an expansion, and also by the small but measurable mass gain that provides the basis of the RHX dating method. The rate of the RHX reaction increases with increasing temperature. Here we describe comprehensively the effects of temperature on the RHX process in relation to the dating methodology. We deal in turn with the kinetic model of the RHX reaction, the temperature dependence of the RHX rate, and the influence of varying environmental temperature on the RHX mass gain. We define an effective lifetime temperature and show how this is calculated from an estimated lifetime temperature history. Historical meteorological temperature data are used to estimate the lifetime temperature history, and this can be adjusted for long-term climate variation. We show also how to allow for the effects of burial in archaeological sites on the temperature history. Finally we describe how the uncertainties in estimates of RHX age depend on the estimates of temperature history and effective lifetime temperature.
