A theoretical policy model is presented that combines regional dynamic CGE modeling and optimal control to explore the role of local government taxation and expenditure in enhancing regional growth. It contributes to the regional CGE literature by explicitly solving for an optimal policy and augments earlier regional optimal control models by adding endogenous optimization of producer and consumer agents in response to endogenously determined prices. Results of three policy regimes are analyzed in terms of gains in the objective function, impacts on income inequality, and sensitivity to model parameterization.  相似文献

The subject of admiralty law may have lost much of its luster over the years, but during the first decades of the nation's existence this branch of the law provided a vehicle for establishing foreign policy principles that helped protect the new nation. The admiralty cases that reached the U.S. Supreme Court in the mid-1790s were important to administration policy in the realm of foreign affairs and to the Court's own development as an independent arm of the national government.  相似文献

Taking as points of inspiration Peter Parish’s 1989 book, Slavery: History and Historians, and Angela Davis’s seminal 1971 article, “Reflections on the Black Woman’s Role in the Community of Slaves,” this probes both historiographically and methodologically some of the challenges faced by historians writing about the lives of enslaved women through a case study of intimate partner violence among enslaved people in the antebellum South. Because rape and sexual assault have been defined in the past as non-consensual sexual acts supported by surviving legal evidence (generally testimony from court trials), it is hard for historians to research rape and sexual violence under slavery (especially marital rape) as there was no legal standing for the rape of enslaved women or the rape of any woman within marriage. This article suggests enslaved women recognized that black men could both be perpetrators of sexual violence and simultaneously be victims of the system of slavery. It also argues women stoically tolerated being forced into intimate relationships, sometimes even staying with “husbands” imposed upon them after emancipation.  相似文献

In August 2016, a multidisciplinary team conducted the first archaeological survey of the deep-water (829 m) wreck of the ex-USS Independence (CVL22) using the remotely operated vehicles Argus and Hercules. The survey provided 34 h of direct observation with video and still camera documentation of the wreck, which the previous year had been initially identified with a limited three-dimensional sonar survey of the site. The 2016 assessment added considerably to an understanding of changes to Independence after its use as a target vessel for the 1946 atomic bomb tests at Bikini Atoll, as a radiological laboratory, training facility, and finally as a receptacle for “nuclear waste” prior to its scuttling off California in January 1951. The location and detailed examination of the wreck, along with additional archival research, offers a more nuanced definition of the carrier’s role within the context of the Cold War between the USSR, its adversaries and the race to establish nuclear supremacy, as well as site formation processes and ongoing biological colonization of the wreck site. As well, no evidence of residual radiological contamination was noted during the mission.  相似文献

British and Irish Mesolithic studies have long been characterized by a reliance on broad-scale lithic typologies, both to provide chronologies, and in discussion of ‘cultural’ groups. More recently, traditional narrative structures—period definitions of ‘Early’ and ‘Late’, or culture typologies—have been complemented by a host of other evidence. This has included new studies of site stratigraphy, evidence for seasonality, and material culture chaîne opératoire chronologies, which place a greater emphasis on both temporal precision and the lived experiences of Mesolithic peoples. This paper will consider how the study of organic artefacts forces these narrative scales into acute focus, and presents an opportunity to explore the challenges in synthesizing different forms of data. We discuss how the evidence from sites in Ireland and Britain allows for new approaches, and highlight some of the challenges that this evidence presents, not least the perennial issue of moving from site-specific data to broader narratives. While the nature of earlier prehistoric evidence makes this an especially obvious issue for Mesolithic studies, it is one which generally besets archaeology. We suggest that in order to move beyond this in earlier prehistoric studies specifically, we need to make better use of all evidence sources, however seemingly prosaic, including antiquarian collections in museums, and chance and casual finds. Only by including the raft of available data, and recognizing its utility beyond the sum of individual apparently uninspiring parts, can we begin to move from generalizing narratives to more nuanced archaeological understandings of past material worlds.  相似文献

This paper investigates reactions to a proposed municipal solid waste facility in Southern Ontario supposed to be a low-level, low probability risk using the risk society framework, developed independently by Beck (1992a, 1992b) and Giddens (1990, 1991). Residents often view risk from environmental hazards as high despite expert assurances that risks are low. The appeal of risk society as a general framework is that it connects quantitative risk assessment (QRA) and the social construction of risk (SCR) to show how individuals and social structures reflexively alter and are altered by conflicts over (actual/potential) technological hazards. The analysis involves 30 in-depth face-to-face interviews with residents in Caledon, Ontario, contextualized by interviews with proponent experts (n=4) from the government organization responsible for conducting the siting process. The risk society framework, although developed primarily to describe the effects of high-consequence global hazards, seems well suited to describing local level, low-consequence hazards. The siting process involved a series of fateful moments which upset people's security in particular ways of life. The proposed landfill and the process itself threatened the very nature of what people valued and expected from their community. However, this study raises a concern that the risk society played out at the local/regional level may exacerbate inequalities in the distribution of risks relative to benefits from technological environmental hazards. This stands in contrast with Beck's (1992a) notion that the risks from hazards are equitably distributed within the risk society.  相似文献
