The neighboring abandoned villages of Palmetto Point and Middle Island, on the northwest of Saba, Dutch Caribbean, relied upon rainwater caught in cisterns as their primary source of potable water. The island of Saba is located in the northern Lesser Antilles, and thus is subject to a rainy and dry season in the course of a year. Using measurements of the village cisterns and their respective catchments combined with variations in monthly rainfall data over the course of a year, a study of water replenishment versus water consumption is possible for Palmetto Point and Middle Island. As a result, fluctuations in population in villages with measurable, finite supplies of potable water allow a researcher to determine the viability of the villages at particular points in time, and the resultant effects on internal economies and social dynamics during these periods.  相似文献

Abstract

The male/female sex ratio (SR) and its age-specific patterns vary considerably across time and place. The SR generally begins male-biased at birth and becomes female-biased later in life, but this relationship should respond to historical trends and events. Temporal trends in SRs remain largely unstudied and formal demographic relationships are not well defined. We (1) define SRs in a life table framework, (2) estimate the age at which the number of males and females achieves parity—the sex ratio crossover (SRX)—using basic life table methods, and (3) explore historical and international patterns in these trends. Using publicly-available data from the Human Mortality Database, we construct SR and SRX measures from period and cohort life tables. Analyses explore temporal patterns for seven countries in different global regions since 1850. Overall temporal trends show the SRX advancing to older ages. The SRX also appears to respond to historical events such as wars and epidemics. The measure is simple to construct from life table data, and provides additional insight into the historical context of gender dynamics.  相似文献

This paper will demonstrate how a focus upon the practices and interactions in and of the everyday lives of mothers of learning disabled children can provide rich insights into the position of a group of children who may not be able to conform to appropriate ways of behaving and using space. This focus will illustrate how the spatial practices and experiences of the mothers and their children are shaped by the reactions of others present and the mothers' interpretations of, and responses to, those reactions. It will, moreover, raise questions about the position of older learning disabled children whose unconventional behaviour in public spaces can threaten disorder.  相似文献

In the course of gathering oral histories from women who servedin the Navy and Coast Guard during World War II, an unusualconversational pattern has emerged. The women almost invariablydiminish the importance of their wartime contributions; a commonrefrain is "I didn’t do anything important." Their individualexperiences, as revealed during the interviews, belie that assertion.In this paper, I will use the women's words to parse what ismeant by this rhetorical move. Do the women really believe theydid not do anything important? If so, why do they find it necessaryto participate in the very public process of oral history, placingtheir names and life stories within the historical record? Consideringboth the content and the context of the women's words from afeminist pragmatist philosophical base will help explain thisseemingly incongruent act. This article demonstrates that thewomen do not really mean to belittle their life experiences(and military service), but instead are using the phrase asa way to acknowledge society's expectations. The oral historyinterview, meanwhile, is used by the women to not only placetheir experience into the historical record but also to affirmthe importance of their wartime work.  相似文献
