ABSTRACT. In this paper, a conditional location problem on a weighted network is examined. Attraction functions are defined and the problem is formulated as a mixed integer program. A method which simultaneously locates an additional facility on the given network and optimizes its weight is then described. A numerical example is provided.  相似文献

ABSTRACT

The US government has long held that cultural goods and services represent an economic sector like any other and should be liberalized. The American cultural and digital industries enjoy a strong competitive advantage and constitute a leading export sector. This US stance has antagonized many countries pursuing cultural policies. This has led the US government to soften its trade strategy and accept financial measures, as well as a broader array of ‘traditional’ cultural regulatory instruments. At the same time, the United States insists on the absence of restrictions in digital networks, through which cultural contents are to be increasingly distributed and accessed. Under the negative-list negotiating approach, whereby everything is liberalized save for specific exceptions, states parties to US trade agreements have secured a varying array of measures. However, only a handful, essentially industrial countries, have secured digital exceptions, the latter coupled with conditions raising questions concerning their applicability.  相似文献

Women are demonstrably under-represented at senior levels in Australia's international affairs. Empirical evidence shows a continuing gender imbalance in leadership positions, including in the Department of Foreign Affairs and Trade, the Department of Defence and academia. Two explanations commonly offered are that women are less motivated or lack interest in ‘hard’ international relations. These explanations are found to be unconvincing, given studies showing similar levels of ambition and interest at recruitment. Four alternative explanations are offered to account for the scarcity of female leaders in Australia's international affairs: the legacy of direct discrimination, continued indirect discrimination, inadequate support for women who balance work and family responsibilities, and socially constructed gender norms. Instead of the subject matter of international relations being too ‘hard’, or inherently masculine, it appears that it is the combined impact of these factors that has made it ‘hard’, or difficult, for women to progress to senior levels. In order to show how these barriers can be overcome, three case studies are presented of women who have achieved senior positions: Professor Emeritus Helen Hughes, Her Excellency Ms Penny Wensley and Professor Hilary Charlesworth. These examples suggest strategies that women can use to further their careers and measures that can be implemented in workplaces to improve the representation of senior women in Australia's international affairs.  相似文献

Through ethnographic and historical analysis of the Negev region of Israel, this article examines competitive planting as a common tool in land conflicts. In a context of disputed land ownership, some Bedouin Arab residents plant crops in defiance of government policy. Government enforcers of land‐use regulations destroy many of these crops and engage in counterinsurgent tree‐planting. I suggest that planting is such a potent tactic because it draws on “environmental idioms” of agricultural labor, the rootedness of trees, and a fundamental Jewish‐Arab opposition that have been central to the development of both Israeli and Palestinian nationalisms. For Bedouin Arabs, whose relationship to both nationalisms has long been contested, the multivalent symbolism of planting makes it a particularly promising tactic for asserting land claims. Further, I contend that these plantings demonstrate both the power of environmental idioms to structure land claims along ethnic lines and the creative potential of participants to challenge dominant environmental discourses by adding new connotations.  相似文献

This article examines the construction of Peter Damian's (c.1007–72) Vita Beati Romualdi (c.1042) as a piece of eleventh-century hagiography. Peter Damian was an erudite hermit, monk and reformer whose ideas on spiritual perfection helped to shape the ideals of the so-called ‘Gregorian Reform’ movement in the eleventh century. This article aims to contribute to recent historiography on the eleventh century through a re-examination of this important piece of hagiography, which has not been more thoroughly considered by medievalists since 1957 in Tabacco's critical edition. This article suggests that, through the biography of St Romuald, Peter Damian sought to promote the example of the Desert Fathers in formulating a more rigorous monastic rule, not only for his hermits at Fonte Avellana, but also for a wide monastic and lay audience. It also argues that there existed a gradual evolution in monastic ideology from the tenth century onwards, sponsored by ascetics like Damian who strove constantly to lead a more austere existence based on the Desert tradition and more particularly the Life of St Antony. In particular, the article pays attention to how Damian, as a hagiographer, was engaged in the construction of Romuald's sanctity.  相似文献

The dramatic topography of the Dordogne Valley region of southwestern France has long been recognized as an influence on prehistoric human settlement and subsistence patterns. Previous research on late Pleistocene settlement patterns in this region implies that, as cold-adapted higher-ranked resources became scarce in the lowlands, site location in the Dordogne and adjacent river valleys should shift towards higher-elevation areas during the period from 18,000 to 6500 years BP. This study employs a GIS-based analysis to evaluate the changing settlement patterns in the Dordogne region at this time. While no significant changes in elevation were found during this period, site elevation variance does appear to increase significantly between the Magdalenian and the Sauveterrian. Explanations for this finding are explored using zooarchaeological data from Moulin du Roc, one of the sites in the data set. Results suggest that the Magdalenian period in the Dordogne may not have been as resource-rich as is often assumed.  相似文献

The Security and Prosperity Partnership of North America (SPP), signed by Canada, Mexico and the United States in March 2005, proposes a dramatic reshaping of the continent. This is no simple plan for the intensification of economic and security cooperation. The SPP is much more expansive and includes quality of life issues such as education, science and technology, the environment, and health. But what does it mean that there is an emergent concern with biopolitics, that is, with the lives and bodies of the region's citizens, at the trilateral level? How are these citizens being imagined in the new regional vision? What are the implications for states and sovereignty? This paper addresses these questions by turning first to the trope of “partnership” as it emerges in the SPP, and then to the ways that borders and population mobility are being construed. The discourse of “partnership” signals a new political rationality that is reconfiguring the relationship between the North American states, their markets and their citizens. The repercussions for citizens and citizenship are especially significant, and are most clearly apparent vis‐à‐vis border policies, as I discuss in the following section. While external borders are being hardened against most foreign nationals, mobility across internal borders is becoming more differentiated: more penetrable for some, and impassable for others. The SPP thus promotes a divisive and striated regional space that will help perpetuate the ongoing tensions around illegal immigrants and undocumented workers in North America.  相似文献
