LES VERRES ANCIENS: LA QUESTION DE LA DATABILITÉ PAR THERMOLUMINESCENCE

La plupart des échantillons de verres archéologiques ne sont pas datables par thermoluminescence. Une analyse des causes limitant l'extension de la datation par thermoluminescence aux verres anciens montre que celles-ci sont directement issues de caracteristiques de l'etat vitreux. Toutefois. dans certains cas particuliers, la datation est possible. Most archaeological glass samples cannot be dated using thermoluminescence (TL). An analysis of the causes which limit the extension of the TL dating method to ancient glass shows that these causes come from the vitreous state characteristics. Nevertheless in some cases, dating is still possible.     

FORECASTING TURNING POINTS IN METROPOLITAN EMPLOYMENT GROWTH RATES USING BAYESIAN TECHNIQUES

In this paper, I adapt to the regional level a Bayesian approach developed by Zellner, Hong, and Min (1990) to analyze forecasts of turning points in a multicountry setting. The techniques applied to a regional setting treat the individual metropolitan areas in the same way that Zellner, Hong, and Min treated countries. The findings in this study indicate that the techniques and models employed by Zellner, Hong, and Min work just as well at the metropolitan-area level as they did in the multicountry setting. The best models, from those studied here, forecast around 70 percent of the downturns and 80 percent of the upturns correctly, which compares favorably to the performance of the same techniques in Zellner, Hong, and Min.     

Women and children last: the poverty and marginalization of one-parent families

The spatial distribution and socioeconomic status of one-parent families in Great Britain and Australia are described, and reasons for the increase in this type of family are analyzed. The author finds that "one-parent families, largely composed of women and children, constitute one of the most rapidly-growing family types. Evidence from Britain and Australia reveals their extreme marginalization in the labour market, and their concentration into public housing. These problems are related to patriarchal structures within society, particularly the expectations of traditional gender roles and the segregation of women's job opportunities."
