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

ABSTRACTThe 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

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

Gilbert M. Joseph 《Cold War History》2019,19(1):141-170
This essay reviews the burgeoning literature on Latin America’s distinctive variant of the Cold War since about 2000. First, it examines a watershed of recent collaborations between Latin American area specialists and foreign relations scholars, which has dramatically transformed Latin American Cold War Studies. Then, it focuses on two of the more fertile veins in that scholarship: first, the notion that the region’s Cold War should be placed in a broader historical context, which scholars are increasingly referring to as Latin America’s “long Cold War,” and second, the long Cold War’s multivalent cultural dimension. If study of the Latin American Cold War has become something of a growth industry in the last 15 years, its leading edge may well be efforts to tease out the complex, power-laden cultural processes, relationships, exchanges, and institutional forms that antedated and shaped Latin America’s Cold War proper (c. 1947 to the early 1990s), and had consequences beyond the conflict’s denouement. 相似文献

Mackness, B.S., Black, K.H. & Price, G.J., 1.10.2014. Occurrence of Euowenia grata (De Vis, 1887) (Diprotodontidae, Marsupialia) from the Pliocene Spring Park Local Fauna, northeastern Queensland. Alcheringa 39, 000?000. ISSN 0311-5518Ten specimens including several dentaries and maxillae, recovered from the Pliocene Spring Park Local Fauna, northern Australia, are referred to the diprotodontine Euowenia grata (De Vis). The fossils exhibit minimal dental wear and reveal new characters that are unrecognizable in the holotype. The remains represent at least three animals, effectively doubling the previous number of individuals known for this rare megaherbivore. The new records also provide a significant northern geographic range extension for the species and allow an assessment of intraspecific variation, sexual dimorphism and phylogenetic relationships for the species. Euowenia grata is most similar in morphology to the monotypic Pliocene diprotodontid Meniscolophus mawsoni.Brian S. Mackness [deceased] and Karen H.

The term futurism was used in aesthetic circles during the first decade of the twentieth century throughout Europe. The broad use of the term has sometimes led to critical attempts to link the various "futurisms" together into a coherent whole. In my article, I compare and contrast Alomar's Catalan futurism with the Italian futurism associated with Filippo Tommaso Marinetti (1876-1944). Although the two futurisms share the name and, to some extent, similar philosophical backgrounds, their foundational documents or manifestos are more different than they are similar, and Alomar's futurism cannot and should not be critically subordinated to Marinetti's Italian one. My article addresses what is futurist in Alomar's thought as well as its unique regionalist underpinnings that find no analogue in other European futurisms. 相似文献
