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

Much recent scholarship has identified an urgent need to address distribution opportunities for Australian cinema in a digital age. In trying to understand why Australian film policy has been beleaguered by complacency for distribution, this paper looks abroad to see what precedents and attitudes exist in distribution-related cultural policy. Why hasn’t support for distribution and exhibition been the touchstone of cultural policy for national cinemas? Why has policy support for the production sector prevailed, when distribution is the film industry’s key zone for profit? This paper surveys international policy examples of what governments are doing beyond the production realm. It examines legal interventions into the distribution realm, including direct state measures such as subsidies, levies, quotas and import restrictions, indirect state aid, and cultural initiatives by film funding bodies that stimulate audience engagement in the distribution and exhibition sectors. The paper combines these primary sources of film policy information with film historians’ accounts to provide a comparative analysis of national film distribution policies. It then examines the politics underlying the various policy frameworks, before mapping out an alternative strategy for the future of policy in Australia that is equipped to deal with the huge changes in digitalisation. 相似文献

The original ceramics typology developed for Younge/Western Basin Tradition Springwells phase (ca. AD 1160–1420) assemblages included three variants known as Macomb Linear, Macomb Interrupted Linear, and Springwells Net Impressed ceramics. This discussion considers how subregional variation in Springwells decorative styles reflects participation in a larger regional social network. 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

Substantial changes to the built environment, urbanisation patterns, and societal norms have contributed to limiting children's opportunities for being independently mobile. Several linear causal pathway models have been developed to understand the influences on children's independent mobility; however feedback loops between and within the various levels of influence cannot be modelled using such an approach. The purpose of this paper is to refine the interrelationships of factors related to children's independent mobility, taking into account earlier models, broader contextual factors, recent children's geographies literature, and feedback loops. Systems model components were informed by attributes known to influence children's independent mobility, related qualitative findings, and the development of a framework that could lend itself to multilevel modelling approaches. This systems model may provide a useful structure for identifying how best to develop and monitor interventions to halt the declining rates of children's independent mobility. 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
