A problem which has arisen in discussions of an elm-disease explanation for the Neolithic elm decline has been the lack of fossil records of Scolytus scolytus (F.) (elm bark beetle), which is the main carrier of the fungus which causes the present epidemic of Dutch Elm Disease. Now, the discovery of wing cases of two individuals from elm decline deposits at Hampstead Heath, London, proves that the beetle was present in Britain during this episode. The deposits in which it occurs are described, and the various implications for elm disease causing, aiding or at least occurring during this stage of the early Neolithic are discussed.  相似文献

Policies concerning undocumented immigrants are inevitably ambivalent, creating uncertainty and confusion in the implementation process. We identify a clear example of this ambivalence —U.S. law setting standards for determining the credibility of asylum seekers—that resulted in an increase in asylum grants despite policymakers' intention to make it harder for individuals to obtain the status. We argue that this law, The REAL ID Act of 2005, sent mixed messages to immigration judges (IJs), street-level bureaucrats who implement immigration policy. It increased IJ discretion, but set vague limits. We theorize that IJs, behaving in a bounded rationality framework, use their professional legal training as a short-cut and look primarily to the courts for guidance. Our evidence supports our argument. After the passage of the REAL ID Act, IJ decision-making is more closely aligned with the preferences of their political and legal principals, and, in the final score, the federal circuit courts are the winners.  相似文献

ABSTRACT This paper examines the impacts of measures to reduce emissions from buses, cars, and two‐wheelers in Mumbai, India. We have considered three possible policies: conversion of diesel buses to CNG, an increase in the price of gasoline and a tax on vehicle ownership. Our results suggest that the most effective policy to reduce emissions from passenger vehicles—in terms of the total number of tons of PM10 reduced—is to convert diesel buses to CNG. The conversion of 3,391 diesel buses to CNG would result in an emissions reduction of 663 tons of PM10 per year, 14 percent of total emissions from transport.  相似文献

In a study at the largest northeastern Iowa food pantry between 2004 and 2006, we found that neither working nor accessing government benefits has a meaningful impact on lessening the odds that a person will need long‐term food assistance. In other words, the working poor are at greater risk for making recurrent visits to the food pantry than those who do not work. Pantry clients who work are more likely to have sacrificed food to pay for other life necessities. Moreover, government benefits do not seem to provide an adequate food safety net. As a result, nonprofits are experiencing increased pressure to fill the gap. If we wish to maintain the government responsibility to alleviate hunger in our country, benefits for eligible citizens must be increased or food assistance nonprofits need more government support. Otherwise we should face the fact that as an undeclared public policy, our society tolerates hunger.  相似文献

This paper considers the ideals and activism of the fin de siècle feminist organisation, the Women's Emancipation Union (WEU). Active between 1891 and 1899, the WEU held a prophetic vision of the future and an appraisal of women's subjection more comprehensive than any contemporary feminist group. Members were the first to link the possession by women of their bodily autonomy directly to the acquisition of the parliamentary vote, and thus redefined the terms upon which citizenship was constructed. One member raised the matter of armed insurrection in support of the women's franchise, an issue which would have serious implications for the future of suffragist campaigns. The political roots of WEU members lay chiefly within the utopian‐socialist and Radical‐liberal traditions, but it was an organisation which resisted party‐political allegiance to become anchored in the Progressive movement. Adopting what has been defined as the ‘muckraking’ tradition associated with Progressive authorship, the WEU suffragists constructed a rhetoric of resistance to women's subjection from social, sexual, economic and political standpoints. Many points they raised, including for a woman's right to consent to maternity to be enshrined in law, were to become the bedrock of the philosophy of the militant suffragette movement.  相似文献

This essay analyzes the representation and cross-fertilization of natural and spiritual landscapes in Andrés Pérez de Ribas's Historia de los Triumphos de Nuestra Santa Fee (1645), a massive history of Jesuit evangelization in northwestern New Spain. Pérez de Ribas confers a major role to the natural world by deploying its wonders as well as its utilitarian riches in the service of imperial expansion and conversion, resignifying native landscapes in the process. The essay argues that Pérez de Ribas uses a ‘double optics’ of empirical observation and religion in order to make the northern periphery visible to readers at the centers of imperial power, and to participate in the Jesuit enterprise of knowledge making that was so much a part of their global enterprise.  相似文献

ABSTRACT

This essay argues that Pope Boniface VIII (1294–1303) used clothing in a highly intentional and performative manner to communicate his status and authority. His audience, however, was quite limited – essentially, the small community of those who aspired to hold or influence the power of the Holy See – and the messages conveyed were not particularly complex. Attempting a reception history of papal attire c.1300, the essay surveys remarks regarding clothing in late thirteenth- and early fourteenth-century chronicles and analyses in depth the evidence of two sources: ambassadorial reports to King James II of Aragon (1291–1327) and the De electione et coronatione sanctissimi patris domini Bonifatii pape octavi of Cardinal Jacopo Caetani Stefaneschi (c.1270–1343). A suggestive finding is that performativity, or the highly theatrical use of garments, appears to have been used by Boniface VIII to foster dissemination of simple communications across great distances.  相似文献

URBAN/REGIONAL ECONOMICS AND RURAL DEVELOPMENT   总被引:1,自引:0,他引:1  
ABSTRACT How does the research about rural economies in developed countries compare to urban/regional economics? What can the new generation contribute? This paper briefly reviews modern research concerning rural development in one country, the U.S., and reports indicators of U.S. rural distress. It examines the market forces and market failures that cause rural distress and that may limit the applicability of existing urban/regional theories to rural problems. A feast of uniquely rural issues that require—and should inspire—theoretical innovations in rural, urban, regional, and spatial economics are identified and discussed.  相似文献
