In the concluding episode of the Third Branch of the Mabinogi, the Welsh nobleman Manawydan takes the (pregnant) mouse that he has captured to the magically significant site Gorsedd Arberth and prepares to hang her for theft, according to the law. As he prepares the gallows, various figures attempt to intervene until finally a ‘bishop’ redeems his transformed wife by disenchanting the land, freeing Manawydan’s companions, and swearing not to take vengeance. We argue that this scene is strikingly similar to the famous ballad widely attested all over Europe, ‘The Maid Freed from the Gallows’, a parallel which not only illuminates this episode in the Mabinogi, but also suggests how the Welsh storyteller used traditional material in shaping these narratives.  相似文献

Among the wide range of geographic analysis methods are service coverage models. These location analytic approaches have been invaluable for better understanding existing (and past) conditions, deriving creative plans, and developing policy for addressing associated societal problems. Increasingly sophisticated spatial information and better knowledge about interrelated mechanisms of process and behavior have made it possible to enhance coverage models, enabling more nuanced formalizations to be devised. This has proven both important and essential in many ways. Mathematical details associated with service coverage models are derived to highlight evolving capabilities. Empirical results are presented in order to illustrate the significance and substantive importance of advanced location analytics capabilities.  相似文献

When traditional methods for measuring economic welfare are scarce or unreliable, heights and BMIs are now well-accepted measurements that represent biological conditions during economic development. Weight, after controlling for height, is an additional measure for current net nutrition. Little is known about how weights varied among Mexicans living in the nineteenth century American West. Between 1870 and 1920, average Mexican weight was low and remained constant. Mexican farmers had the heaviest weights, and unskilled worker weights were low. Weight of Mexican-born individuals were higher than Mexicans born in the United States at low weights but lower at high weights. For combined characteristics, weight varied the most with age, an uncontrollable characteristic, indicating that nineteenth century Mexican current net nutrition varied the most with factors over which they had no control.  相似文献
