THERMOLUMINESCENCE DATING OF MATERIALS WHICH EXHIBIT ANOMALOUS FADING

This article reports a generalised and systematic approach to the thermoluminescence (TL) dating of samples which suffer from anomalous fading. We hypothesise that the TL signal from each mineral phase is composed of a stable and an unstable portion. The decay of the unstable TL is accelerated thermally, until only stable TL remains. The dating is then carried out on this stable signal. The results, on four known-age, coeval samples, exhibiting gross anomalous fading (25-50% loss over a few days), indicate that many, if not all, samples may successfully be dated with this approach.     

WORDSWORTH and LAKE DISTRICT TOURISM: ROMANTIC RESHAPING OF LANDSCAPE

Creative literature colours popular perception of landscape and place. An analysis of English romanticism, Wordsworth's poetry in particular, illustrates how the transformation of an actual landscape into a literary landscape helped change attitudes toward wilderness and natural beauty. The romantic ideology fostered impressions of an idyllic, untamed eden. In response to public fascination with this mythologized and emotional portrait of place, a tourist landscape emerged. Thus even those unfamiliar with romantic literature are encouraged to see particular landscapes from a literary perspective.
Dans la formation d'une perception envers un paysage ou un endroit, un élément important est souvent la littérature imaginaire. Une analyse du romantisme anglais, en particulier la poésie de Wordsworth, démontre comment la transformation d'un paysage actuel sous une forme littéraire contribua fortement à un changement d'attitude envers la nature. Cette idéologie romantique encouragea la notion d'un jardin d'Eden encore sau-vage. la fascination entretenue par ce portrait mythique créa finalement un environnement touristique. Même ceux qui n'ont guère connaissance en littérature romantique ont une vision d'un paysage particulier qui dérive dune perception littéraire.     

Net migration,unemployment, and the business cycle

"An empirical test of the effects of exogenous shocks upon a region's population size is conducted in the framework of an equilibrium locational model. The model emphasizes the separation of endogenous from exogenous factors, a point omitted in most empirical studies of aggregate migration. Exogenous changes are manifested in the local relative cost of living and the local relative unemployment rate. Hypotheses are tested using a national sample of youth, in addition to census, data [for the United States]. Surprisingly, a simple measure of the size of shock to a regional economy has the greatest explanatory power compared to more sophisticated measures based on prior business cycles."     

NETWORK EQUILIBRIUM MODELS OF URBAN LOCATION AND TRAVEL CHOICES: A RETROSPECTIVE SURVEY*

ABSTRACT The origins and development of the network equilibrium problem are traced and interrelated. Two principal formulations are considered the network equilibrium problem with variable travel demand, and the combined model of trip distribution and traffic assignment. The relation of these models to subsequent developments concerning mode choice, residential location, estimation of origin-destination tables from link flows and stochastic route choice are then reviewed.     

MEASURING THE EFFECT OF COST VARIATION ON INDUSTRIAL OUTPUTS*

ABSTRACT. This paper introduces the household interactive variable input-output (HIVIO) model to measure the effect of cost variation on industrial outputs. The model produces a variety of cost elasticities that separate out impacts on industrial prices, imports, and outputs, with “own” and “cross” elasticity components. Like the conventional input-output multipliers, these cost elasticities can be useful parameters to evaluate the substituting behavior of firms and consumers. By using the 1980 Korean input-output transactions table, we find the wage and import price effects on industrial prices, outputs, and import demands.
