Studies of dog remains focused on the Iron Age southern Levant generally highlight their unique nature in the archaeological context, specifically in relation to their post-mortem exploitation. Here we review the published archaeological and textual data to evaluate the current understanding of dogs’ roles in their Iron Age settings. The analysis reveals that dogs are relatively common in the archaeological record, having been reported at 66% of sites. This study further contextualizes this presence in light of their co-occurrence with caprine and wild taxa. The significant number of dog remains indicates that they were part of the social matrix of a village. While dogs have been viewed as ‘unclean’ or pariah, based on certain textual references in the Hebrew Bible, we assert, on the basis of the archaeological record, that they were part of the life of the village, functioning as herders, guards and occasionally hunters.  相似文献

The archaeological record of prehistoric Cyprus is rich, diverse, well-published, and frequently enigmatic. Regarded by many as a bridge between western Asia and the Aegean, Cyprus and its past are frequently seen from scholarly perspectives prevalent in one of those two cultural areas. Its material culture, however, differs radically from that of either area. Apart from the early colonization episodes on the island (perhaps three during the pre-Neolithic and Neolithic), evidence of foreign contact remains limited until the Bronze Age (post-2500 B. C.). This study seeks to present the prehistory of Cyprus from an indigenous perspective, and to examine a series of archaeological problems that foreground Cyprus within its eastern Mediterranean context. The study begins with an overview of time, place, and the nature of fieldwork on the island, continues with a presentation and discussion of several significant issues in Cypriot prehistory (e.g., insularity, colonization, subsistence, regionalism, interaction, social complexity, economic diversity), and concludes with a brief discussion of prospects for the archaeology of Cyprus up to and beyond 2000.  相似文献

The issue of fairness often is central within environmental policy debates. The recent proliferation of state and local comparative risk projects for informing the selection of environmental policy priorities offers an appropriate setting to explore the issue of procedural fairness in risk-based decisionmaking. This paper describes and evaluates the process by which one of the initial state comparative risk projects, Washington's “Environment 2010,” attempted to include a broader range of participants in identifying, assessing, and generating preferred management strategies for a wide range of environmental hazards. The Washington case study suggests that comparative risk projects can be fairer procedurally, but that significant barriers remain. Noting that greater procedural fairness does not necessarily produce greater substantive fairness, the paper concludes that more attention needs to be directed at the process by which comparative risk projects translate their consensus upon risk priorities into subsequent actions.  相似文献

Speakers at the Third Social, Humanitarian, and Cultural Committee Assembly held in December 1994 maintained that power sharing between women and men is still intolerably low and that economic hardship, abuse, and discrimination remain. One speaker announced that society needs to do more to challenge obstacles to women's advancement: poverty, violence, access to resources, women's rights, education, and health. She asserted that, for this reason, the Fourth World Conference on Women scheduled for September 1995 in Beijing must succeed. Discussions and action at the December assembly will constitute a major part of the groundwork for the Beijing Conference. The Committee debate centered on the advancement of women as a cause and effect of development. The 1994 World Survey on the Role of Women in Development shows that economic development may be complexly connected with advancement of women. In societies where women have progressed, the economy tends to grow steadily, while, in societies where women cannot fully participate in development, the economy is stagnant. The Assembly called on the Commission on the Status of Women to ensure that the Platform for Action recognize and incorporate older women's concerns and contributions to development into its strategies, programs, and policies. It also called for countries to protect women migrant workers from violence and corrupt recruitment practices. It condemned the illegal trafficking of women and girls across borders for sexual or economic oppressive and exploitative purposes and for other illegal activities (forced domestic labor, false marriages, clandestine employment, and false adoption).  相似文献

ABSTRACT. The problem of locating a point that is as far as possible from arcs and nodes of a network is investigated. Each arc or node may have a different multiplicative factor (weight) for its distance. A graphical solution approach, as well as a computational algorithm, is presented.  相似文献
