The social safety net in the United States consists of a variety of programs administered by both federal and state governments. Although the populations served by social programs such as Medicaid and consumer bankruptcy likely overlap, policymakers tend to look at individual programs unilaterally and often fail to communicate appropriately with legislators and political leaders at differing levels of government. The result of such an incremental approach to policy reform is a fragmented social safety net system in the United States. In this study, the relationship between two social programs belonging to the larger social safety net is examined, and recommendations for policymakers are offered. 相似文献

你的行为出卖了你的心,这有时或许是好事。至少,它让你通过以下问卷知道,你对旅行的依赖程度和哪个目的地更适合你。下个假期来临时,你能很从容地有个准备,而不是因不知道去哪儿消磨它而抓狂。 相似文献

<正>At 9:50 in the morning on Sep.13th,2014,the eleven of us in"the Interview team to Southwest Tibet"finally arrived at the Nyingchi Mainling Airport,the most difficult airport in China at which to land a plane,despite it being at Tibet's lowest altitude.Setting our feet on the land of the Yarlung Tsangpo River Valley,we thought of what it was like in the air as we traversed the alpine region,where the narrowest space was no further than 4 相似文献

This paper explores the impact of animal manure application on the δ15N values of a broad range of crops (cereals and pulses), under a range of manuring levels/regimes and at a series of locations extending from northwest Europe to the eastern Mediterranean. We included both agricultural field experiments and areas where ‘traditional’ farming is practised. Our aim is to ground-truth interpretation of δ15N values in archaeobotanical crop remains as evidence of past growing conditions and husbandry practices. The results confirm the potentially radical impact of manuring on δ15N values in cereals, depending on manuring level, but indicate only a slight effect on pulses, which can fix atmospheric nitrogen. The expected geographical trend towards greater δ15N with increasing climatic aridity is not apparent, probably because the growing conditions for crops are ‘buffered’ through crop management. Each of these observations has fundamental implications for archaeobotanical interpretation of δ15N values as evidence of land use practices and (together with analysis of bone collagen/tooth enamel in potential consumers) palaeodiet. 相似文献
